[Combination therapy in oncology (multimodal treatment) in pancreatic tumors].

The majority of patients with pancreatic cancer have systemic disease already at diagnosis, and nearly all patients will develop recurrence following radical resection. Thus, surgical treatment alone is insufficient. The paper focuses on adjuvant multimodal treatment and reviews the current status of pre- and postoperative chemoradiation, intraoperative radiotherapy (IORT), adjuvant chemotherapy, and regional infusion therapy. Studies in this area are hampered by often being non-randomized and with too few patients included. Overall there presently is no adjuvant multimodal treatment which can be suggested for routine use. However, two ongoing prospective randomized studies (ESPAC-1 and an EORTC study) will have enough statistical power to give reliable information on the topic. It is hoped that these and other studies will form the basis for further proper clinical trials on multimodal treatment in pancreatic cancer with the aim at long last to improve the extremely poor survival in these patients.

Multimodal features and prognostic risk assessment in locally advanced gastric cancer patients following neoadjuvant therapy based on machine learning algorithms: a multicenter study.

BACKGROUND: Neoadjuvant therapy (NAT) is recommended for locally advanced gastric cancer (LAGC), but some patients respond poorly. We aimed to construct a multimodal model integrating CT images, transcriptomic sequencing, and clinicopathological data to assess prognosis in LAGC patients receiving NAT. MATERIALS AND METHODS: This multicenter study included 505 LAGC patients who underwent NAT. Radiomic features were extracted from preoperative CT images of 505 patients. RNA-seq was performed on 277 post-NAT specimens, with additional data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases (n = 804). Patients were divided into training (168 cases), internal validation (72 cases), and external validation cohorts. Machine learning algorithms identified key radiomic, molecular, and clinical features associated with NAT response, which were then integrated into a multimodal model to predict overall survival (OS) and disease-free survival (DFS). RESULTS: Six radiomic and three molecular features significantly associated with NAT response were selected. Radiomic risk (hazard ratio [HR]: 4.0, P < 0.001) and molecular risk (HR: 7.1, P < 0.001) were independent prognostic factors. By integrating radiomic risk, molecular risk, and clinical characteristics, a multimodal model (MuMo) was constructed.The C-index results (OS, C-index = 0.855; DFS, C-index = 0.786) demonstrated that MuMo outperformed the single-modality models and ypTNM staging.Mechanistic analysis suggested that the efficacy of neoadjuvant therapy was significantly enriched in immune-inflammatory pathways. CONCLUSIONS: MuMo can effectively predict postoperative survival risk in LAGC patients receiving NAT, serving as a powerful tool for optimizing prognostic assessment.

Multimodality treatment of thymoma: a prospective study.

BACKGROUND: Thymomas are a heterogeneous group of tumors. Treatment of invasive lesions is not well standardized. The aim of this study is to propose a clinicopathologically based protocol for multimodality therapy. METHODS: Between 1965 and 1988, we operated on 83 patients with thymoma who did not receive standardized adjuvant therapy. In 1989, on the basis of the retrospective analysis of the data, we started a multimodality therapy protocol and used it for 65 patients. Twelve patients had medullary thymoma (11 stage I and 1 stage II), 13 had mixed type (6 stage I and 7 stage II), and 40 had cortical thymoma (4 stage I, 11 stage II, 12 stage III, and 13 stage IV). We considered three groups. Group I (n = 18 patients), benign thymoma, included stage I and II medullary and stage I mixed thymomas; radical resection with no adjuvant therapy was performed. Group II (n = 22), invasive thymoma, included stage I and II cortical and stage II mixed thymomas; postoperative chemotherapy plus radiotherapy was always administered. Group III (n = 25), malignant thymoma, comprised stage III and IV cortical thymomas and stage III mixed thymomas; resectable stage III lesions were removed, and highly invasive stage III and stage IV lesions underwent biopsy, neoadjuvant chemotherapy, and surgical resection; postoperative chemotherapy and radiotherapy was administered to all patients. RESULTS: The 8-year survival rate for patients in stages I, II, III, and IV was 95%, 100%, 92%, and 68%, respectively. Patients with medullary thymoma had a 92% 8-year survival rate; those with mixed type, 100%; and those with cortical thymoma, 85%. Group I had an 8-year survival rate of 94%; group II, 100%; and group III, 76%. Survival was compared with that of patients operated on before 1989: differences were not significant for group I; survival improved in group II (100% versus 81%; p = not significant); and group III showed significant improvement (76% versus 43%; p < 0.049). CONCLUSIONS: Multimodality treatment with neoadjuvant chemotherapy and adjuvant chemotherapy plus radiotherapy may improve the results of radical resection and the survival of patients with invasive and malignant thymoma.

Pleural space perfusion with cisplatin in the multimodality treatment of malignant mesothelioma: a feasibility and pharmacokinetic study.

INTRODUCTION: Malignant pleural mesothelioma is an ideal model for testing new locoregional multimodality approaches because of its aggressive local behavior. METHODS: This study was planned to investigate the feasibility, safety, and pharmacokinetics of a multimodality therapy including an operation, pleural space perfusion (60 minutes) with cisplatin (100 mg/m2), hyperthermia (41. 5 degrees C), and postoperative radiotherapy (55 Gy to chest wall incisions). The effects of the extent of resection and perfusion temperature on cisplatin pharmacokinetics were evaluated. Ten patients with epithelial or mixed, stage I or II, malignant pleural mesothelioma underwent the following procedures: group A (3 patients), pleurectomy/decortication and normothermic pleural space antineoplastic perfusion; group B (3 patients), pleurectomy/decortication and hyperthermic perfusion; and group C (4 patients), pleuropneumonectomy and hyperthermic perfusion. Operations were selectively applied depending on tumor extent. Platinum levels were serially measured by atomic absorption in systemic blood, perfusate, lung, and endothoracic fascia. RESULTS: The overall procedure was completed in every case, without any death or toxicity. No lung damage was demonstrated after treatment. Major complications included 1 wound infection and 1 diaphragmatic prosthesis displacement. The mean peak platinum plasma levels were reached within 45 to 60 minutes after perfusion was started. Systemic drug concentrations were greater after pleurectomy/decortication than after pleuropneumonectomy (P =.006). The local tissue/perfusate ratio of platinum concentrations tended to be higher after hyperthermic perfusion rather than normothermic perfusion. CONCLUSION: This multimodality approach is feasible, pharmacokinetically advantageous, and safe enough to undergo further clinical investigations.

Improving treatment planning accuracy through multimodality imaging.

PURPOSE: In clinical practice, physicians are constantly comparing multiple images taken at various times during the patient's treatment course. One goal of such a comparison is to accurately define the gross tumor volume (GTV). The introduction of three-dimensional treatment planning has greatly enhanced the ability to define the GTV, but there are times when the GTV is not visible on the treatment-planning computed tomography (CT) scan. We have modified our treatment-planning software to allow for interactive display of multiple, registered images that enhance the physician's ability to accurately determine the GTV. METHODS AND MATERIALS: Images are registered using interactive tools developed at the University of North Carolina at Chapel Hill (UNC). Automated methods are also available. Images registered with the treatment-planning CT scan are digitized from film. After a physician has approved the registration, the registered images are made available to the treatment-planning software. Structures and volumes of interest are contoured on all images. In the beam's eye view, wire loop representations of these structures can be visualized from all image types simultaneously. Each registered image can be seamlessly viewed during the treatment-planning process, and all contours from all image types can be seen on any registered image. A beam may, therefore, be designed based on any contour. RESULTS: Nineteen patients have been planned and treated using multimodality imaging from November 1993 through August 1994. All registered images were digitized from film, and many were from outside institutions. Brain has been the most common site (12), but the techniques of registration and image display have also been used for the thorax (4), abdomen (2), and extremity (1). The registered image has been an magnetic resonance (MR) scan in 15 cases and a diagnostic CT scan in 5 cases. In one case, sequential MRs, one before treatment and another after 30 Gy, were used to plan patient's initial fields and boost, respectively. Case illustrations are shown. CONCLUSIONS: We have successfully integrated multimodality imaging into our treatment-planning system, and its routine use is increasing. Multimodality imaging holds out the promise of improving treatment planning accuracy and, thus, takes maximum advantage of three dimensional treatment planning systems.

Locally advanced breast cancer: early results of a randomised trial of multimodal therapy versus initial hormone therapy.

The aim of this study was to investigate initial treatment of locally advanced breast cancer. Patients were randomised to "multimodal" therapy (pre-operative chemotherapy, Patey mastectomy, flap irradiation and adjuvant hormone therapy) (n = 55), or initial "hormone" therapy (n = 53) with further therapy upon tumour progression. The objective response to chemotherapy was 57% (31/54) after four cycles. Of patients on hormone therapy, 36% (19/53) had an objective response and 32% (17/53) disease stasis at a 6 month assessment. At a median 30 months follow-up, there was no notable difference in development of metastases or survival: only 6 patients have uncontrolled loco-regional relapse (4 "hormonal", 2 "multimodal"). The number of treatments per patient required for this loco-regional control was lower in the "hormone" group (mean 2.13 versus 4.20 in the "multimodal" group). This small study has shown that the use of consecutive therapies, with the aim of tumour control, does not appear to compromise outcome in comparison with initial "multi-modal" therapy. Adopting such a policy may allow some patients to avoid unnecessary treatments.

Demonstration of accuracy and clinical versatility of mutual information for automatic multimodality image fusion using affine and thin-plate spline warped geometric deformations.

This paper applies and evaluates an automatic mutual information-based registration algorithm across a broad spectrum of multimodal volume data sets. The algorithm requires little or no pre-processing, minimal user input and easily implements either affine, i.e. linear or thin-plate spline (TPS) warped registrations. We have evaluated the algorithm in phantom studies as well as in selected cases where few other algorithms could perform as well, if at all, to demonstrate the value of this new method. Pairs of multimodal gray-scale volume data sets were registered by iteratively changing registration parameters to maximize mutual information. Quantitative registration errors were assessed in registrations of a thorax phantom using PET/CT and in the National Library of Medicine's Visible Male using MRI T2-/T1-weighted acquisitions. Registrations of diverse clinical data sets were demonstrated including rotate-translate mapping of PET/MRI brain scans with significant missing data, full affine mapping of thoracic PET/CT and rotate-translate mapping of abdominal SPECT/CT. A five-point thin-plate spline (TPS) warped registration of thoracic PET/CT is also demonstrated. The registration algorithm converged in times ranging between 3.5 and 31 min for affine clinical registrations and 57 min for TPS warping. Mean error vector lengths for rotate-translate registrations were measured to be subvoxel in phantoms. More importantly the rotate-translate algorithm performs well even with missing data. The demonstrated clinical fusions are qualitatively excellent at all levels. We conclude that such automatic, rapid, robust algorithms significantly increase the likelihood that multimodality registrations will be routinely used to aid clinical diagnoses and post-therapeutic assessment in the near future.

Urologic and sexual morbidity following multimodality treatment for locally advanced primary and locally recurrent rectal cancer.

AIMS: In the treatment of patients with locally advanced primary or locally recurrent rectal cancer much attention is given to the oncological aspects. In long-term survivors, urogenital morbidity can have a large effect on the quality of life. This study evaluates the functional outcome after multimodality treatment in these patient groups. PATIENTS AND METHODS: Between 1994 and August 1999, 55 patients with locally advanced primary and 66 patients with locally recurrent rectal cancer were treated with multimodality treatment: i.e. high-dose preoperative external beam radiation therapy, followed by extended surgery and intraoperative radiotherapy. The medical records of the 121 patients were reviewed. To assess long-term urogenital morbidity, all patients still alive, with a minimum follow-up of 4 months, were asked to fill out a questionnaire about their voiding and sexual function. Seventy-six of the 79 currently living patients (96%) returned the questionnaire (median FU 14 months, range 4-60). RESULTS: The questionnaire revealed identifiable voiding dysfunction as a new problem in 31% of the male and 58% of the female patients. In 42% of patients after locally advanced primary and 48% after locally recurrent rectal cancer treatment bladder dysfunction occurred. The preoperative ability to have an orgasm had disappeared in 50% of the male and 50% of the female patients, and in 45% of patients after locally advanced primary and in 57% after locally recurrent rectal cancer treatment. CONCLUSION: Multimodality treatment for locally advanced primary and recurrent rectal cancer results in acceptable urogenital dysfunction if weighed by the risk of uncontrolled tumour progression. Long-term voiding and sexual function is decreased in half of the patients. Preoperative counselling of these patients on treatment-related urogenital morbidity is important.

Effect of preemptive multimodal analgesia for arthroscopic knee ligament repair.

BACKGROUND AND OBJECTIVES: Administration of analgesic medication before surgery, rather than at the completion of the procedure, may reduce postoperative pain. Similarly, administration of multiple analgesics, with different mechanisms of action, may provide improved postoperative pain control and functional recovery. The purpose of our study was to compare pain scores and intravenous opioid consumption after outpatient anterior cruciate ligament (ACL) reconstruction in patients who received a multimodal drug combination (intravenous [IV] ketorolac, intra-articular morphine/ropivacaine/epinephrine, and femoral nerve block with ropivacaine) either before surgery or immediately at the completion of the surgical procedure. METHODS: Forty patients presenting for same-day arthroscopic ACL repair using a semitendinosis tendon graft were included in this study. The patients were randomized to receive the following drugs either 15 minutes before skin incision or immediately after skin closure: (1) Ketorolac 30 mg IV. (2) Intra-articular injection of 20 mL ropivacaine 0.25% + morphine 2 mg and epinephrine 1:200,000. (3) Femoral nerve block with 20 mL ropivacaine 0.25%. Verbal pain scores were obtained in the postanesthesia care unit (PACU) and on postoperative days 1, 3, and 7. IV patient controlled analgesia (PCA) morphine consumption in the PACU was also recorded. RESULTS: Verbal pain rating scores were lower in group I (preemptive) for 2.0 hours after arrival in the PACU. There was no difference between groups in pain scores on postoperative days 1, 3, and 7. Mean IV PCA morphine consumption in the PACU was lower in group I (6.4 mg) versus group II (12.3 mg), P <.05. CONCLUSION: Preemptive, multimodal administration of our 3-component analgesic drug combination resulted in lower pain scores during the initial stay in the PACU unit and lower consumption of IV PCA morphine in the PACU. However, pain scores were similar in both groups on postoperative days 1, 3, and 7; thus, there was no measurable long-term advantage associated with preemptive multimodal drug administration.

Stroop interference based on the multimodal correlates of haptic size and auditory pitch.

In a preliminary experiment subjects were asked to explore three wooden knobs of different sizes and to rate each one on a series of 7-point scales. The results confirmed that an object may possess a number of multimodal qualities that are contingent on its haptic size. The pattern of intercorrelations between the qualities was consistent with the pattern that is observed when subjects respond to pure auditory tones varying in pitch. For example, small (high-pitched) sounds, like small objects, are judged to be sharp, thin, light, weak, fast, tense, and bright. The main experiments used a paradigm based on the Stroop interference effect. Subjects were required to press one of two keys as quickly as possible depending on which of four possible words appeared in the centre of the screen. A 50 Hz or a 5500 Hz tone accompanied each test word, and subjects responded on two keys that differed in size. Subjects were found to respond more slowly when either the pitch of the incidental sound or the size of the key on which they responded was incongruent with the multimodal features represented by the test word. The results confirm that people are automatically and immediately sensitive to the multimodal features of a stimulus when direct sensory evidence for the features is absent.

mmContext: an open framework for multimodal contrastive learning of omics and text data.

SUMMARY: Multimodal approaches are increasingly leveraged for integrating omics data with textual biological knowledge. Yet there is still no accessible, standardized framework that enables systematic comparison of omics representations with different text encoders within a unified workflow. We present mmContext, a lightweight and extensible multimodal embedding framework built on top of the open-source Sentence Transformers library. The software allows researchers to train or apply models that jointly embed omics and text data using any numeric representation stored in an AnnData.obsm layer and any text encoder available in Hugging Face. mmContext supports integration of diverse biological text sources and provides pipelines for training, evaluation, and data preparation. We train and evaluate models for a RNA-Seq and text integration task, and demonstrate their utility through zero-shot classification of cell types and diseases across four independent datasets. By releasing all models, datasets, and tutorials openly, mmContext enables reproducible and accessible multimodal learning for omics-text integration. AVAILABILITY AND IMPLEMENTATION: Pretrained checkpoints and full source code for our custom MMContextEncoder are available on Hugging Face huggingface.co/jo-mengr. The Python package github.com/mengerj/mmcontext provides the model implementation and training and evaluation scripts for custom training. The releases for the publication can be accessed via zenodo: adata_hf_datasets: doi.org/10.5281/zenodo.19185217 and mmContext: doi.org/10.5281/zenodo.19185493.

Multimodal medullary neurons and correlational linkages of the respiratory network.

This study addresses the hypothesis that multiple sensory systems, each capable of reflexly altering breathing, jointly influence neurons of the brain stem respiratory network. Carotid chemoreceptors, baroreceptors, and foot pad nociceptors were stimulated sequentially in 33 Dial-urethan-anesthetized or decerebrate vagotomized adult cats. Neuronal impulses were monitored with microelectrode arrays in the rostral and caudal ventral respiratory group (VRG), nucleus tractus solitarius (NTS), and n. raphe obscurus. Efferent phrenic nerve activity was recorded. Spike trains of 889 neurons were analyzed with cycle-triggered histograms and tested for respiratory-modulated firing rates. Responses to stimulus protocols were assessed with peristimulus time and cumulative sum histograms. Cross-correlation analysis was used to test for nonrandom temporal relationships between spike trains. Spike-triggered averages of efferent phrenic activity and antidromic stimulation methods provided evidence for functional associations of bulbar neurons with phrenic motoneurons. Spike train cross-correlograms were calculated for 6,471 pairs of neurons. Significant correlogram features were detected for 425 pairs, including 189 primary central peaks or troughs, 156 offset peaks or troughs, and 80 pairs with multiple peaks and troughs. The results provide evidence that correlational medullary assemblies include neurons with overlapping memberships in groups responsive to different sets of sensory modalities. The data suggest and support several hypotheses concerning cooperative relationships that modulate the respiratory motor pattern. 1) Neurons responsive to a single tested modality promote or limit changes in firing rate of multimodal target neurons. 2) Multimodal neurons contribute to changes in firing rate of neurons responsive to a single tested modality. 3) Multimodal neurons may promote responses during stimulation of one modality and "limit" changes in firing rates during stimulation of another sensory modality. 4) Caudal VRG inspiratory neurons have inhibitory connections that provide negative feedback regulation of inspiratory drive and phase duration.

Selective spatial attention in vision and touch: unimodal and multimodal mechanisms revealed by PET.

Two positron-emission tomography (PET) experiments explored the neural basis of selective spatial attention in vision and touch, testing for modality-specific versus multimodal activations due to attended side. In the first study, either light flashes or finger vibrations were presented bilaterally. Twelve healthy volunteers were scanned while sustaining covert attention on the left or right hemifield within each modality. The main effect for attending right minus left, across both modalities, revealed bimodal spatial attention effects in the left intraparietal sulcus and left occipitotemporal junction. Modality-specific attentional effects (again, for attending right vs. left) were found in the left superior occipital gyrus for vision, and left superior postcentral gyrus for touch. No significant activations were seen for attending left minus right. The second study presented only tactile stimuli, manipulating whether the eyes were open or closed, and including passive stimulation and rest baselines. The unimodal activation for tactile spatial attention in the left superior postcentral gyrus was replicated. The bimodal activation of the left intraparietal sulcus observed in the first study was now found for touch, but only when the eyes were open (hands visible), apparently confirming its multimodal nature. These results reveal mechanisms of sustained spatial attention operating at both modality-specific and multimodal levels.

Aims and methodological problems in multimodal treatment studies.

The paper outlines the growing acceptance and use of multimodal treatment approaches to treat a variety of psychiatric disorders in childhood and adolescence. It then explores some of the problems of multimodal treatment studies. Problems in assessing outcome of efficacy of the interventions, particularly as they pertain to specific interventions and particular areas of functioning are discussed as well as the issues of appropriate control and comparison groups. The problems with regard to appropriate control and comparison groups are explored with respect to diagnosis and interventions. Finally, an ongoing multimodal treatment study of children with attention deficit hyperactive disorder is used to illustrate how some of the problems described can be solved.

Ten-year outcome of patients with advanced epithelial ovarian carcinoma treated with cisplatin-based multimodality therapy.

PURPOSE: At the end of the 1970s it was thought that advanced epithelial ovarian cancer (EOC) could be cured by multimodality treatment using surgery, cisplatin-based combination chemotherapy, and radiotherapy (RT). Such multimodality treatment was used as standard therapy at our institution. Our long-term results are reviewed. PATIENTS AND METHODS: One hundred ninety-five previously untreated patients with stage III or IV EOC were treated between April 1979 and December 1982. All patients were to have debulking surgery, when feasible, followed by the administration of doxorubicin and cisplatin at 50 mg/m2 every 3 weeks until a total dose of doxorubicin of 450 mg/m2 had been reached. RT was used in addition in patients with disease remaining after the chemotherapy. Maintenance chemotherapy with oral cyclophosphamide and hexamethylmelamine (altretamine) was administered to patients who did not have a documented histologic complete remission. RESULTS: The 10-year overall and failure-free survivals were 4% and 8%, respectively. The median overall survival was 2 years. The achievement of a histologic complete response (n = 32) did not equate to cure because 20 (63%) of the patients eventually relapsed. Multivariate analysis identified residual disease of greater or less than 2 cm as the only independent prognostic factor. CONCLUSIONS: Our multimodality treatment program was noncurative for the majority of the patients. Innovative therapies are needed before we can hope to cure such disease.

Stage III neuroblastoma over 1 year of age at diagnosis: improved survival with intensive multimodality therapy including multiple alkylating agents.

PURPOSE: A nonrandomized, single-arm trial was conducted to assess the efficacy of multimodality therapy including intensive chemotherapy with multiple alkylating agents in the treatment of children with Evans stage III neuroblastoma older than 1 year at diagnosis. PATIENTS AND METHODS: Twenty-five patients with a median age of 18 months at diagnosis were treated with multimodality therapy including surgery and chemotherapy using either nitrogen mustard (mechlorethamine), doxorubicin, cisplatin, dacarbazine (DTIC), vincristine, and cyclophosphamide (MADDOC) or cisplatin and cyclophosphamide induction followed by maintenance MADDOC (induction MADDOC) protocols. Sixteen of 25 patients also received radiotherapy to the tumor bed and primary lymph nodes. Event-free survival (EFS) was compared with that reported previously in the literature. N-myc amplification was evaluated prospectively and the Shimada classification was evaluated retrospectively as potential prognostic factors. RESULTS: We report a 72% EFS (95% confidence interval +/- 18%) with a median follow-up of 85 months. EFS was significantly worse for patients with tumors demonstrating N-myc amplification (P = .018). Patients classified as favorable according to the Shimada system experienced a significantly better EFS (P = .04), but unfavorable patients still maintained a 60% EFS. CONCLUSION: Intensive multimodality treatment including MADDOC and induction MADDOC chemotherapy provides a very good EFS for children older than 1 year who have stage III neuroblastoma. Children classified as favorable according to the Shimada system have a better prognosis. Patients whose tumors demonstrate N-myc amplification have a poor prognosis despite therapy.

High-dose multimodality therapy with autologous stem-cell support for stage IIIB breast carcinoma.

PURPOSE: Women with locally unresectable and inflammatory breast carcinoma (IBC) have an approximately 30% 5-year disease-free survival (DFS) rate with conventional multimodality therapy. A short but dose-intensive multimodality phase II trial was designed in an attempt to improve outcome in stage IIIB disease. Mastectomy was performed after high-dose therapy to evaluate pathologic response to treatment. METHODS: Women with newly diagnosed disease received four 2-week cycles of doxorubicin 90 mg/m2 with granulocyte colony-stimulating factor (G-CSF), followed by cyclophosphamide 6,000 mg/m2, thiotepa 500 mg/m2, and carboplatin 800 mg/m2 (CTCb) with marrow and peripheral-blood progenitor cell (PBPC) support. Local therapy consisted of mastectomy and radiotherapy. Tamoxifen (5 years) was begun if the patient was estrogen receptor-positive (ER+). RESULTS: Fifty women (46 stage IIIB [91% IBC], four stage IIIA) entered the study and 47 are assessable. Ten had mastectomy before any systemic therapy (seven with pathologic IBC, three with residual tumor after mastectomy). Eighty percent received full-dose doxorubicin with 60% on schedule. Clinical response rates to induction were 15% complete response (CR), 5% very good partial response (VGPR), 59% partial response (PR), and 21% minor response (MR)/stable disease (SD). Mastectomy after CTCb in 37 patients showed a 14% pathologic CR rate, 29% microscopic foci in breast and/or axilla, and 57% gross tumor. Fifteen (32%) patients have relapsed (median, 17 months post-CTCb). The 30-month DFS is estimated at 64%. For those in pathologic CR, with microscopic, or with gross disease remaining after CTCb, the 30-month DFS is estimated at 100%, 70%, and 38%, respectively. Those with zero, one to three, or > or = four positive nodes at axillary dissection had a median DFS of 31, 18, and 13 months, respectively. CONCLUSION: This short but dose-intensive multimodality approach for stage IIIB breast carcinoma is feasible with encouraging results to date.
