[Local recurrence of breast cancer: prognostic factors, effect of adjuvant therapy].

UNLABELLED: Local recurrence after treatment of operable breast cancer occurred in about 20% of the patients before adjuvant therapy became common. The incidence of local recurrence is high during the first 2 years of follow-up, becomes lower afterwards, and is less than 1% after 10 years follow-up. Some primary tumor characteristics have been recognized as risk factors for the development of a local recurrence: size of the primary tumor, its histology and malignancy grade, number of involved axillary lymph nodes. The type and extent of primary tumor treatment, and additional adjuvant therapy are also factors influencing the frequency of local recurrence. Data from MD Anderson Hospital and from the Ludwig Study III are used to show the impact of adjuvant therapy upon local recurrence frequency. CONCLUSION: local recurrence after treatment of breast cancer is becoming less frequent, especially after introduction of adjuvant therapy. The question of additional systemic therapy after excision of local recurrences is still open, and is studied in a clinical trial of the Swiss Group of Clinical Cancer Research.

[Magnetic resonance tomography diagnosis of plexiform fibrohistiocytic tumor].

A case report on a 30-year old female patient who underwent resection of a haemangiopericytoma followed by radiation therapy in 1988 is presented. 6 months ago a space-occupying lesion was detected within the radiation field, which was classified as a plexiform fibrohistiocytic tumour (PFT). On MRI PFT showed the similar signal intensities as the muscles in T1, as well as T2-weighted images. After gadolinium-DTPA no enhancement within the tumour could be measured. Based on its exclusively dermal and subcutaneous location, and its signal behaviour uncommon for a malignant soft tissue mass, PFT must be included in differential diagnosis in any examining for local tumour recurrence.

Alternative therapy for elderly patients with breast cancer.

Breast cancer treatment has undergone significant changes in concept, concurrent with alterations in our understanding of cancer biology and natural history. Within the last 10 years, oncologists have brought into question the traditional Halstedian concepts of the natural history of breast cancer and its appropriate management. The goal of treatment, once a primary cancer is detected in the breast, is to prevent metastasis and subsequent death of the patient. One hundred forty-two female patients over the age of 65 with histologically confirmed breast cancer were treated at Lankenau Hospital from 1982 to 1990. We treated 32 women over the age of 65 with quadrantectomy and tamoxifen as the sole form of therapy. No radiation, standard chemotherapy, nor axillary dissection was utilized. A cohort of 110 women of similar age, treated for breast cancer with "standard therapy" (total mastectomy or "segmental resection" and radiation with axillary nodal dissection) during the same time period, were also analyzed retrospectively. All segmental resections were followed by standard radiation doses to the ipsilateral breast and draining nodal basins with a local boost. Twenty-nine of 32 patients in the quad + tam group were available for follow-up 1 to 8 years following treatment (mean 52 months). The cumulative overall survival was 67 per cent and disease-free survival 92 per cent. No patient developed local recurrence. Follow-up analysis of the 110 women treated in "standard fashion" was complete in 88 patients 1 to 8 years post-treatment (mean 56 months). Cumulative overall survival was 82 per cent and disease-free survival 83 per cent. Local recurrence was noted in five per cent.(ABSTRACT TRUNCATED AT 250 WORDS)

Selective irradiation for the treatment of recurrent ovarian carcinoma involving the vagina or rectum.

OBJECTIVE: The aim of this study was to evaluate the role of selective irradiation in the management of recurrent or persistent ovarian carcinoma involving the vagina or rectum after initial surgery or surgery and chemotherapy. METHODS: Twenty-eight patients with recurrent or persistent vaginal and/or perirectal disease from ovarian carcinoma received selective irradiation and were evaluated for local control, survival, and quality of life. Seventy-nine percent had previously received various combinations of chemotherapy after initial surgery. At recurrence, 68% of the 28 patients were treated with external beam irradiation only, 7% with brachytherapy only, and 18% with both external beam irradiation and brachytherapy. In addition, 50% of the patients received various combinations of chemotherapy before or after radiotherapy and 3 patients received additional surgery. RESULTS: Vaginal bleeding was controlled in all patients and a complete symptomatic response was achieved in 79% of the symptomatic patients. Survival after recurrence at 2 years was 57% for patients who had no liver or extra-abdominal metastasis at the time of radiotherapy (21 patients) and 0% for patients who had liver or extra-abdominal metastases (7 patients). Median survival of 5 patients with abdominal and pelvic disease and 16 patients with no extrapelvic disease at the time of recurrence was 2.16 (0.16-10.67) and 2.08 (0.58-27) years, respectively, after recurrence. Fifty percent of the 16 patients without extrapelvic disease had a complete response to radiotherapy (CR group) and the remaining had a partial response or stable disease (non-CR group). The 1-year survival after salvage irradiation in this same group was 100% in the CR group and 37.5% in the non-CR group (P < 0.0001). There are 4 long-term survivors in the CR group who are still alive in excess of 5 years after salvage radiotherapy. Thirty-five percent (5/14) of the patients with pelvic disease only recurred in the unirradiated upper abdomen. CONCLUSIONS: Radiation can be considered an effective treatment option for patients with vaginal and/or perirectal recurrences of ovarian carcinoma. It offers excellent palliation to patients with disseminated disease and may result in both local control and long-term survival in patients with nondisseminated disease. This location may represent a sanctuary site from chemotherapy. Pelvic irradiation alone may be effective salvage and the addition of brachytherapy may improve local control, particularly in patients with disease confined to the pelvis who undergo debulking or chemotherapy.

Segmental mastectomy without radiotherapy. Short-term follow-up.

Short-term treatment failures following 43 segmental mastectomies without radiation therapy and 157 total mastectomies for primary operable breast cancer Stages I and II (T1-2, N0-1, M0) are compared. Although not randomized by design, the patients in the two treatment groups were of similar age and had tumors of comparable histologic type, size, grade, and stage. The overall recurrence rates in an average follow-up of 24 months (range, 6-48 months) were 5% for patients treated by standard mastectomy and 19% for those treated by segmental mastectomy. Recurrence rates in patients with the more commonly encountered carcinomas of 11 to 50 mm in size treated by surgery alone were 7.5% for total mastectomy and 28.0% for segmental mastectomy. Nearly all of this difference relates to a higher frequency of local recurrence in the segmental mastectomy group (P = less than 0.005). Recurrent disease in both groups developed at comparable intervals, averaging 17 months for segmental mastectomy and 16 months for total mastectomy. Using a serial subgross technique, which permitted detection of clinically unsuspected involvement of resection margin by microscopic foci of carcinoma, it was noted that such involvement was an important prognostic indicator for local recurrence. Five of eleven breast resections with this feature developed local recurrence, compared with only 3 of 32 without such involvement of the resection margin.

Predictors of reexcision findings and recurrence after breast conservation.

PURPOSE: To identify predictors of reexcision findings and local recurrence in the setting of breast-conserving therapy with radiation. METHODS: The records of 535 patients who underwent breast-conserving surgery followed by radiation for Stage I or II cancer between 1972 and 1996 were reviewed. The mean follow-up period for surviving patients without evidence of recurrence is 6 years. Various clinical and pathologic prognostic factors were examined for significance with regard to reexcision findings and recurrence rates. Pathologic margin status was classified as negative, close (<or=2 mm), positive, or indeterminate. RESULTS: The pathologic margin status was the most important predictor of local recurrence. The freedom from local relapse (FFLR) at 6 years was 97% for patients with negative pathologic margins and 86% for all others (p < 0.0001). There was no significant difference in recurrence rates among patients with close, positive, or indeterminate margins. However, the use and sequencing of systemic therapy affected recurrence rates among these patients. For patients with close, positive, or indeterminate margins, the crude risk of local recurrence was 4% among patients who received tamoxifen or received chemotherapy integrated with or after radiation. The risk of local recurrence was 16-29% among the patients with close, positive, or indeterminate margins who did not receive systemic therapy or who received radiation after completion of chemotherapy. Local recurrence rates were low in patients with negative margins (2-8%) regardless of the use of systemic therapy or its timing. The presence or absence of residual disease at reexcision did not predict recurrence as long as the final margins were negative. Among patients who underwent reexcision before radiation, extensive intraductal component (EIC) (p = 0.0001) and young patient age (p = 0.03) were predictive of residual disease in the specimen. Patients with initially close margins and no EIC had a low risk of residual disease at the time of reexcision, as did patients older than age 65 without EIC. CONCLUSION: Pathologic margin status is the most important predictor of local recurrence after breast conservation with radiation. Patient age and EIC were significant predictors of residual disease at reexcision. The use and timing of systemic therapy appear to influence the risk of local recurrence in patients who do not have negative lumpectomy margins.

Locally recurrent nasopharyngeal carcinoma: treatment results for patients with computed tomography assessment.

PURPOSE: To study the treatment outcome in patients with locally recurrent nasopharyngeal carcinoma as restaged by computed tomography (CT). PATIENTS AND METHODS: One hundred forty patients with CT restaged locally recurrent nasopharyngeal carcinoma were reviewed. Patients were restaged at recurrence according to the AJCC stage classification with the following distribution: T1-T2:30%, T3:19%, T4:51%. Ninety-seven patients received reirradiation; among these 62 had external irradiation, 34 had brachytherapy, and 1 had both. Twelve patients received surgery. Thirty-one patients were treated with palliative intent and received either chemotherapy or supportive treatment only. Overall survival (OAS) and performance-adjusted survival (PAS, defined as surviving with a Karnofsky performance score [KPS] > 50) were calculated by Kaplan-Meier method. Multivariate analysis was performed using the Cox model. RESULTS: The median survival for all patients was 23.8 months. After reirradiation, the 3-yr and 5-yr OAS rates were 46% and 36%, respectively. The corresponding PAS rates were 40% and 28%. The 3-yr OAS rates for recurrent T1-2, T3, and T4 disease after reirradiation were 71%, 42%, and 30%; the corresponding 5-yr OAS rates were 57%, 42%, 17%. The 3-yr and 5-yr OAS rates in patients receiving palliative treatments only were 19% and 0%, respectively. The 3-yr OAS rate after surgery was 42%. In the multivariate analysis, older age, recurrent T3-4 disease, and palliative treatment were unfavorable factors in predicting overall survival, whereas recurrent T3-4 disease, baseline KPS < 70, and palliative treatment were unfavorable factors in predicting PAS. A high complication rate was observed after reirradiation, with 34% of patients developing neurological sequel. CONCLUSION: Aggressive treatment for locally recurrent nasopharyngeal carcinoma is warranted especially for those with disease confined to the nasopharynx. Survival after retreatment for more extensive disease remains poor but was still superior to supportive treatment only. Early diagnosis of local recurrence allows prompt administration of treatment and is associated with better outcome. Future studies should aim at improving the therapeutic ratio in the retreatment of recurrent disease especially in patients with more extensive local recurrence.

Disease recurrence after resection for stage I lung cancer.

OBJECTIVE: To asses the incidence of local recurrence and distant metastases after complete resection for stage I lung cancer in order to predict the predominant prognostic factors. METHODS: We retrospectively reviewed 123 patients with stage I lung cancer who underwent curative resection over a 2-year period between January 1987 and December 1988. There were 83 male and 40 female patients with a mean age of 64.8 +/- 12 years (range between 39 and 82 years). Multivariate analysis of prognostic factors for long term survival was undertaken. RESULTS: T1N0 lesions were found in 34 patients and T2N0 in 89. The histological diagnosis was Squamous carcinoma in 75, Adenocarcinoma in 38, large cell carcinoma in 6 and small cell carcinoma in 4 patients. Pneumonectomy was performed in 27 patients (5 T1 and 22 T2) while 96 required lobectomy (29 T1 and 67 T2). At 5 years 50 patients died. This was due to local recurrence in 12, distant metastasis in 24, second primary in 1, unrelated disease in 3, while the cause was unknown in 10 patients. At 5 years, 10 patients were alive with evidence of recurrence. The mean interval for local recurrence was 19.8 months and for distant metastasis was 18 months. The overall 5 year survival was 67% +/- 4 for T1 and 56% +/- 5 for T2 lesions (NS). The rate of recurrence was significantly less for T1 lesions (P = 0.02). Survival was significantly less for patients requiring pneumonectomy rather than lobectomy (P = 0.01) whether for T1 or T2. CONCLUSION: In stage I lung cancer T2 lesions requiring pneumonectomy for complete resection had a worse prognosis and higher incidence of local recurrence.

Monoclonal antibody A7-superparamagnetic iron oxide as contrast agent of MR imaging of rectal carcinoma.

Superparamagnetic iron oxide (SPIO)-based colloid has been used clinically as a tissue-specific magnetic resonance contrast agent. We coupled monoclonal antibody A7 (Mab A7), which reacts specifically with human colorectal carcinoma, to Ferumoxides (SPIO) and examined the accumulation of this conjugate in xenografted tumours in nude mice. We examined in vitro immunoreactivity of Mab A7 coupled to Ferumoxides and its in vivo distribution in nude mice with human colorectal carcinoma. Magnetic resonance imaging of tumour-bearing nude mice was performed 72 h after injection of A7-Ferumoxides. A7-Ferumoxides retained binding activities that were nearly identical to intact Mab A7. More of the radiolabelled A7-Ferumoxides accumulated in the tumour than normal mouse IgG-Ferumoxides from 12 h onwards after injection (P<0.05). Both A7-Ferumoxides and normal mouse IgG-Ferumoxides disappeared from blood linearly over time. The accumulation levels in normal tissue decreased linearly over time but were lower than levels in tumours from 6 h. In magnetic resonance T2-weighted imaging of the tumour-bearing nude mice, signal intensity was reduced at the margin of the tumour by injection of A7-Ferumoxides. Mab A7 coupled to Ferumoxides is potentially suitable as a magnetic resonance contrast agent for detecting local recurrence of rectal carcinoma.

[Giant cell tumor of bone. An evaluation of 87 patients].

AIM: Giant cell tumor (GCT) of bone is a very peculiar and interesting tumor due to of its biological behavior and the phenomenon of pulmonary metastases of a histologically benign tumor. We present the results of a retrospective study. METHODS: Between 1965 and 2002 we treated 87 patients, 54 women and 33 men, for a GCT of bone. The average age of the patients was 28.2 (range 8-72) years. The median follow-up time was 91 months. 63 patients (72.4%) were hospitalized with a primary tumor. Twelve of these patients (19 %) had a pathological fracture. 24 patients (27.6%) presented with local recurrence. 7 tumors were malignant GCT of bone, 80 tumors were benign. According to the classification of Campanacci, 9 patients (10.3%) were diagnosed in stage I, 42 (48.3%) in stage II, and 36 (41.4%) in stage III. Surgical procedures were intralesional curettage and packing with cement in 36 patients, and bone-grafting in 7. In 35 cases we performed a wide resection, and in nine an amputation. RESULTS: Local recurrence was observed in 11 patients (12.6%), all of them were benign GCT. Local recurrences were followed by an intralesional curettage and bone-grafting in three cases (42.8%), packing with cement in seven (19.4%). Three patients with local recurrence (27.3%) also had synchronous pulmonary metastases. All patients diagnosed with benign GCT are still alive. 3 out of 7 patients with malignant GCT died from progression of metastatic disease. CONCLUSION: To reduce the risk of local recurrence and pulmonary metastases, we recommend an adjuvant therapy of GCT.

[Treatment and treatment results of mouth floor cancers].

The records of 68 patients with cancer of the floor of the mouth were reviewed. 56 patients underwent surgical management, 51 of them got additionally postoperative radiation. The tumour-specific five years' survival for patients with operation was 46%, 57% of treatment failures developed from local recurrence of the tumour. In 52% of all cases there was a spread to the lymphatic system in the histological evaluation. There was high incidence of false negative clinical examinations of the neck. Conservative neck dissection was the procedure of choice for clinically positive lymph nodes and for the elective management of the neck. Only advanced tumours showed involvement of the mandibular bone. Therefore a conservative management of mandibular resection was preferred. Radical tumour extirpation and histological controlling with serial sectioned specimens are methods of avoiding local tumour recurrence.

[Therapy and results of the treatment of breast cancer. A report on 1,003 cases 1970 to 1978].

1003 women with invasive breast carcinoma were treated in the Department of Obstetrics and Gynecology, Medical School Hannover, between 1970 and 1978. In 787 patients modified radical mastectomy was combined with postoperative radiation therapy. In 797 patients, who were observed for at least 5 years, the 5 year survival rate was 63.0%, depending on tumor stage. In spite of intensive loco-regional treatment, local recurrence occurred in 18.0%. For us, that was one among other reasons to discontinue routine postoperative radiation therapy.

Argon beam coagulation as an adjuvant for local control of giant cell tumor.

The argon beam coagulator is gaining popularity as an adjuvant therapy for treatment of giant cell tumors of bone. However, the effectiveness and functional implications of this treatment have not been assessed. To determine whether the argon beam coagulator could be a viable adjuvant treatment option, we examined the recurrence rate and functional outcome of patients with giant cell tumors who were treated with the argon beam coagulator, as an adjuvant to curettage and cementation. Thirty-seven patients who received argon beam coagulation as an adjuvant treatment for giant cell tumors diagnosed between 1993 and 2000 were identified. The median age of the patients was 32 years (range, 16-64 years). The mean followup was 73.7 months (range, 0.5-108 months). Three patients had osseous recurrences (8.3%) and one had a soft tissue recurrence. The 5-year Kaplan-Meier disease-free survival estimate was 87.2% (95% confidence interval, range, 76.3-99.8). No patient had radiographic evidence of arthritis. The average Musculoskeletal Tumor Society score was 28. Short form-36 evaluation showed no change in functional or mental perception in these patients compared with US norms. These data suggest argon beam coagulation as an adjuvant therapy is associated with in a low rate of local recurrence and is a reasonable adjuvant treatment option.

Paget's disease of the nipple as local recurrence after breast-conservation treatment for early-stage breast cancer.

Breast conservation treatment (BCT) for early-stage breast cancer is associated with survival rates comparable with mastectomy but has the risk of ipsilateral breast tumor recurrence, including Paget's disease of the nipple. A small number of cases of Paget's disease presenting as local recurrence following BCT for breast cancer have been previously reported. Between 1977 and 2002, 2181 women with early-stage breast cancer were treated with BCT at the Hospital of the University of Pennsylvania. In this cohort, there were 183 local treatment failures, 4 of which were cases of Paget's disease (2.2%), which are reported herein. These local recurrences developed 1.8, 3.8, 7.3, and 9.7 years after diagnosis of the patients' primary tumors. Three of the 4 primary cancers were invasive ductal carcinomas, with an associated intraductal component, and 1 was ductal carcinoma in situ. All 4 patients were successfully given salvage therapy consisting of mastectomy with or without tamoxifen, with follow-up times of 20.9, 10.6, 3.1, and 3.8 years. Paget's disease as local recurrence after BCT is uncommon and can be treated with salvage therapy if detected early.

[Analysis of the late curative effect of 432 cases with advanced squamous cell carcinoma of the maxillary sinus].

OBJECTIVE: To study the late curative effect of different methods used in the treatment of advanced squamous cell carcinoma of the maxillary sinus (SCMS). METHODS: A retrospective analysis of 432 cases with SCMS was done. Among them, 141 cases were in stage III, 291 in stage IV, 244 were male, 188 were female, and the age ranged from 14 to 87 years. Radiotherapy, operation only and the combined treatment (radiation plus operation) were adopted. RESULTS: The 5-year survival rates were 15.6% in radiation group, 21.7% in operation group, and 40.1% in combined group (40% in the preoperative irradiation group, and 43% in the postoperative irradiation group). The 5-year survival rates were 31.7%, 46.6% and 20% respectively for those involving structures above, below or both above and below the Ohngren line. Among the 238 cases with poor curative effect, 198 had local recurrence. CONCLUSION: Combined treatment was the best choice for advanced SCMS. There were no significant differences in the survival rates between preoperative and postoperative radiotherapy groups. The survival rate might be improved by preoperative radiotherapy with a dose of 50 Gy, or postoperative radiotherapy with doses of 60-70 Gy. The prognosis for those with the tumor located below the Ohngren line was much better than those above the line and those both above and below the line. The key to the successful treatment for maxillary sinus carcinoma is to control the local recurrence effectively.

[Study on local recurrence in patients undergoing curative surgical resection of lung cancer].

Clinical features of recurrence in patients of lung cancer undergoing curative surgical resection were examined with special reference to the local recurrence. Subjects were 308 patients, consisting of 160 adenocarcinomas, 121 squamous cell carcinomas, 15 large cell carcinomas, 12 small cell carcinomas. They underwent curative resection in our department between 1973 and 1987. Local recurrence developed in 54 patients (18%). There was no significant difference in the incidence of local recurrence among the four histological types of carcinoma. According to the pathological stage, the incidence was 9% in stage I, 15% in stage II, and 35% in stages IIIA+IIIB. The local recurrence was subdivided into the following patterns: 1) lymphatic metastases to the hilar, mediastinal, or supraclavicular sites, 2) recurrence at the surgical margin, 3) malignant pleuritis or pericarditis, 4) so-called "endobronchial metastasis". The incidence of recurrence according to the patterns was 15%, 2%, 2% and 1%, respectively. The incidence of recurrence due to lymphatic metastases was correlated significantly with the pN factor but not with the pT factor. Patients with central type lung cancer showed a significantly higher incidence of lymphatic recurrence than patients with the peripheral type. Patients having postoperative radiotherapy to prevent local recurrence showed a lower incidence of lymphatic recurrence than patients having no radiotherapy. In conclusion, lymphatic recurrence was the most frequent pattern in local recurrence after curative resection of lung cancer, and therefore improvements in the operative procedure of lymphatic dissection, as well as in postoperative adjuvant therapy including radiotherapy will be urgently required for the purpose of reducing local recurrence.

[A new application of immunoconjugate to reduce the local recurrence of colorectal cancer].

To examine whether or not immunoconjugate-A7-NCS can contribute for the reduction of local recurrence of colorectal cancer, the present study was undertaken. The study included examination of local retension, lymphatic delivery and inhibitory effect on tumor development after local administration of A7-NCS. The result showed that locally injected A7-NCS showed a high local retension, a high regional lymph node accumulation and a high inhibitory effect on tumor development. This finding indicates that A7-NCS can be a new promising tool for reducing the local recurrence of colorectal cancer.
