The impact of young age on locoregional recurrence after doxorubicin-based breast conservation therapy in patients 40 years old or younger: How young is "young"?

PURPOSE: The aim of this study was to investigate whether patients <35 years old have similar risk of locoregional recurrence after breast conservation therapy compared with patients 35 to 40 years old. METHODS AND MATERIALS: We retrospectively reviewed records of 196 consecutive patients < or =40 years old who received breast conservation therapy (BCT) from 1987 to 2000 for breast cancer and compared outcomes between patients <35 years old with patients 35 to 40 years old. The majority of patients received neoadjuvant chemotherapy as part of their treatment. Multivariate analysis was performed to assess risk factors for locoregional recurrence. RESULTS: After a median follow-up of 64 months, 22 locoregional recurrences (LRR) were observed. Twenty patients developed locoregional recurrence as their first site of relapse. Two patients had bone-only metastases before their locoregional recurrence. On multivariate analysis, age <35 years was associated with a statistically significant increased risk of locoregional recurrence. The 5-year rate of locoregional control was 87.9% in patients <35 years old compared with 91.7% in patients 35 to 40 years old (p = 0.042). CONCLUSIONS: Our finding supports an increased risk of locoregional recurrence as a function of younger age after breast conservation therapy, even among young patients 40 years old and younger.

Incidence and prevention of venous thromboembolism in patients undergoing breast cancer surgery and treated according to clinical pathways.

OBJECTIVE: To minimize treatment variations, we have implemented clinical pathways for all breast cancer patients undergoing surgery. We sought to determine the incidence of postoperative venous thromboembolism (VTE) in patients treated on these pathways. SUMMARY BACKGROUND DATA: Cancer patients have an increased risk of VTE because of a hypercoagulable state. The risk of VTE following breast cancer surgery is not well established. METHODS: We retrospectively reviewed prospectively collected data for all patients who underwent breast cancer surgery and were treated on the clinical pathways with mechanical antiembolism devices and early ambulation in the postoperative period between January 2000 and September 2003. RESULTS: During the study period, 3898 patients underwent 4416 surgical procedures. Seven patients with postoperative VTE within 60 days were identified, for a rate of 0.16% per procedure. Six patients presented with only a deep venous thrombosis or a pulmonary embolism; 1 patient had both. The median time from surgery to diagnosis of VTE was 14 days (range, 2-60 days; mean, 22 days). No relationship was identified between stage of breast cancer or type of breast surgery and development of VTE. Two (29%) of the 7 patients with VTE had received neoadjuvant chemotherapy. VTE treatment consisted of subcutaneous low-molecular-weight heparin (n = 5) or intravenous heparin (n = 2) followed by warfarin. There were no deaths. CONCLUSIONS: VTE following breast cancer surgery is rare in patients who are treated on clinical pathways with mechanical antiembolism devices and early ambulation in the postoperative period. We conclude that systemic VTE prophylaxis is not indicated in this group of patients.

Incidence of anaphylactoid reactions to isosulfan blue dye during breast carcinoma lymphatic mapping in patients treated with preoperative prophylaxis: results of a surgical prospective clinical practice protocol.

BACKGROUND: Severe anaphylactoid reactions to isosulfan blue dye requiring resuscitation are reported to occur in 1.1% of patients with breast carcinoma undergoing sentinel lymphadenectomy. In December 2001, the authors began administering a prophylactic regimen before dye injection to determine whether prophylaxis reduced the incidence of life-threatening reactions. METHODS: All patients were mapped with technetium-99m-labeled sulfur colloid. Those also receiving isosulfan blue dye were administered a glucocorticoid, diphenhydramine, and famotidine intravenously just before or at induction of anesthesia. Adverse reactions at the time of surgery were analyzed. RESULTS: Between December 2001 and July 2003, 1013 consecutive patients underwent sentinel lymphadenectomy for breast carcinoma. Six hundred sixty-seven patients (65.8%) received prophylaxis and isosulfan blue dye, 33 (3.3%) received prophylaxis but no dye, 12 (1.2%) received dye but no prophylaxis, and 301 (29.7%) received no prophylaxis or dye. Blue urticaria and facial edema were observed in 3 (0.5%) of 667 patients receiving prophylaxis and dye and in 1 (8.3%) of 12 patients receiving dye but no prophylaxis. There were no episodes of hypotension, and no patients required vasopressors, ventilatory support, or intensive care observation. Adverse reactions to agents other than blue dye were observed in 2 (0.3%) of 667 patients receiving prophylaxis and dye and in 3 (1.0%) of 301 receiving no prophylaxis and no dye (P = 0.1773). CONCLUSIONS: Preoperative prophylaxis was found to reduce the severity, but not the overall incidence, of adverse reactions to isosulfan blue dye. No life-threatening reactions were noted in patients treated with preoperative prophylaxis. Based on these results, the authors now routinely recommend administration of prophylaxis to patients receiving isosulfan blue for lymphatic mapping and sentinel lymph node biopsy.

Paget's disease of the breast: there is a role for breast-conserving therapy.

BACKGROUND: The optimal surgical management of Paget's disease of the breast remains to be defined. Mastectomy has been the standard of care, but several institutions have recently advocated breast-conserving surgery, particularly for patients with minimal disease. In an effort to develop rational treatment guidelines, we examined our institutional experience with Paget's disease of the breast. METHODS: Patients with Paget's disease of the breast who had surgical therapy at our institution between 1949 and 1993 were reviewed. In addition to patient and tumor characteristics, charts were reviewed for treatment modalities, locoregional recurrence patterns, and survival. Subgroups were compared for differences in survival in both univariate and multivariate analyses. RESULTS: A total of 104 patients met the study criteria. The most common presenting symptoms were nipple discharge and eczematous changes of the nipple/areola complex. Ninety-seven patients (93.2%) had an underlying invasive or noninvasive cancer associated with Paget's disease. Ninety-two patients (88.5%) underwent mastectomy, and 12 (11.5%) had a breast-conserving procedure. On univariate analysis, patients with age <60 years at diagnosis, stage II disease, positive lymph nodes, invasive disease, or a palpable mass had significantly lower 10-year disease-specific and recurrence-free survival. There were four locoregional recurrences (three after mastectomy and one after breast conservation). There were no significant differences in overall, disease-specific, or recurrence-free survival according to the type of surgery. CONCLUSIONS: Paget's disease of the breast is almost always associated with an underlying breast cancer. Breast-conserving approaches result in local control and survival rates similar to those achieved with mastectomy.

Breast conservation after neoadjuvant chemotherapy.

BACKGROUND: The appropriate selection criteria for breast-conserving therapy (BCT) after neoadjuvant chemotherapy are poorly defined. The purpose of the current report was to develop a prognostic index to help refine selection criteria and to serve as a general framework for clinical decision-making for patients treated by this multimodality approach. METHODS: From a group of 340 patients treated with BCT after neoadjuvant chemotherapy, the authors previously determined 4 statistically significant predictors of ipsilateral breast tumor recurrence (IBTR) and locoregional recurrence (LRR): clinical N2 or N3 disease, residual pathologic tumor size > than 2 cm, a multifocal pattern of residual disease, and lymphovascular space invasion in the specimen. The M. D. Anderson Prognostic Index (MDAPI) was developed by assigning scores of 0 (favorable) or 1 (unfavorable) for each of these 4 variables and using the total to give an overall MDAPI score of 0-4. RESULTS: The MDAPI stratified the 340 patients into 3 subsets with statistically different levels of risk for IBTR and LRR after neoadjuvant chemotherapy and BCT. Actuarial 5-year IBTR-free survival rates were 97%, 88%, and 82% for patients in the low (MDAPI overall score 0 or 1, n=276), intermediate (MDAPI score 2, n=43), and high (MDAPI score 3 or 4, n=12) risk groups, respectively (P<0.001). Corresponding actuarial 5-year LRR-free survival rates were 94%, 83%, and 58%, respectively (P<0.001). CONCLUSIONS: Patients with an MDAPI score of 0 or 1, which made up 81% of the study population, had very low rates of IBTR and LRR. The MDAPI enabled the identification of a small group (4%) of patients who are at high risk for IBTR and LRR and who may benefit from alternative locoregional treatment strategies.

Immediate breast reconstruction can impact postmastectomy irradiation.

OBJECTIVE: Immediate breast reconstruction is an attractive option for patients who undergo mastectomy. The purpose of this study was to qualitatively assess the effect of immediate reconstruction on the design of postmastectomy radiotherapy fields at our institution. METHODS: We retrospectively reviewed the records of 152 patients treated at our institution with postmastectomy radiotherapy over a 1-year period. We identified 18 postmastectomy radiotherapy plans in the setting of prior reconstruction. By consensus, 2 board-certified radiation oncologists scored the 18 plans in terms of 4 outcomes: coverage of the chest wall breadth, coverage of the ipsilateral internal mammary chain (IMC) region, minimization of lung exposure, and avoidance of the heart. RESULTS: Only 4 of the 18 plans resulted in optimal treatment of the chest wall breadth and IMC region while well avoiding the heart and lung. Of the remaining 14 plans, 12 compromised coverage of the chest wall breadth medially and/or laterally, and 9 provided no IMC coverage. CONCLUSION: Immediate breast reconstruction may impose limitations on the treatment planning of postmastectomy radiotherapy, particularly in regard to providing broad coverage of the chest wall and IMC region while avoiding excess exposure of the heart and lung.

Metaplastic sarcomatoid carcinoma of the breast with absent or minimal overt invasive carcinomatous component: a misnomer.

Metaplastic carcinomas of the breast are a heterogeneous group of neoplasms ranging from tumors with a predominant component of overt carcinoma and focal mesenchymal differentiation to keratin-positive tumors with pure sarcomatoid morphology. We examined the clinicopathologic features of 22 patients previously diagnosed at M.D. Anderson Cancer Center with metaplastic carcinoma of the breast with pure or almost pure sarcomatoid morphology. Patients were included in the study if their tumors had sarcomatoid morphology and: 1) an invasive carcinomatous component identifiable on hematoxylin and eosin stains comprising less than 5% of the invasive tumor; or 2) associated ductal carcinoma in situ; or 3) immunohistochemical expression of keratin in the sarcomatoid areas. Patients with low-grade fibromatosis-like metaplastic tumors and those who received neoadjuvant chemotherapy were excluded. Axillary lymph node dissection or limited axillary node excision was performed in 17 patients, including 1 patient who had a sentinel lymph node biopsy. Lymph node involvement occurred in only 1 patient and consisted of a single 3.5-mm metastasis. Clinical follow-up was available for 21 patients and ranged from 4 months to 155 months (median follow-up, 35 months). Ten patients experienced local relapse, including 7 of 11 patients treated with breast-conserving surgery, and 9 developed distant metastases, most frequently to the lungs. These findings suggest that metaplastic sarcomatoid carcinomas that lack or have only a minimal overt invasive carcinomatous component have a biologic behavior similar to that of sarcomas. In addition to systemic treatment, early aggressive local therapy is recommended, as these patients have a high rate of local relapse.

Delayed-immediate breast reconstruction.

In patients with early-stage breast cancer who are scheduled to undergo mastectomy and desire breast reconstruction, the optimal timing of reconstruction depends on whether postmastectomy radiation therapy will be needed. Immediate reconstruction offers the best aesthetic outcomes if postmastectomy radiation therapy is not needed, but if postmastectomy radiation therapy is required, delayed reconstruction is preferable to avoid potential aesthetic and radiation-delivery problems. Unfortunately, the need for postmastectomy radiation therapy cannot be reliably determined until review of the permanent tissue sections. The authors recently implemented a two-stage approach, delayed-immediate breast reconstruction, to optimize reconstruction in patients at risk for requiring postmastectomy radiation therapy when the need for postmastectomy radiation therapy is not known at the time of mastectomy. Stage 1 consists of skin-sparing mastectomy with insertion of a completely filled textured saline tissue expander. After review of permanent sections, patients who did not require post-mastectomy radiation therapy underwent immediate reconstruction (stage 2) and patients who required postmastectomy radiation therapy completed postmastectomy radiation therapy and then underwent standard delayed reconstruction. In this study, the feasibility and outcomes of this approach were reviewed. Fourteen patients were treated with delayed-immediate reconstruction between May of 2002 and June of 2003. Twelve patients had unilateral reconstruction and two patients had bilateral reconstruction, for a total of 16 treated breasts. All patients completed stage 1. Tissue expanders were inserted subpectorally in 15 breasts and subcutaneously in one breast. The mean intraoperative expander fill volume was 475 cc (range, 250 to 750 cc). Three patients required postmastectomy radiation therapy and underwent delayed reconstruction. Eleven patients did not require postmastectomy radiation therapy. Nine patients had 11 breast reconstructions (stage 2), six with free transverse rectus abdominis musculocutaneous (TRAM) flaps, one with a superior gluteal artery perforator flap, and four with a latissimus dorsi flap plus an implant. The median interval between stages was 13 days (range, 11 to 22 days). Two patients who did not require postmastectomy radiation therapy have not yet had stage 2 reconstruction, one because she wished to delay reconstruction and the other because she required additional tissue expansion before permanent implant placement. Six complications occurred. The stage 1 complications involved two cases of mastectomy skin necrosis in patients who required post-mastectomy radiation therapy; one patient required removal of the subcutaneously placed expander before postmastectomy radiation therapy and the other patient had a subpectorally placed expander that only required local wound care. The stage 2 complications were a recipient-site seroma in a patient with a latissimus dorsi flap, a recipient-site hematoma in the patient with the superior gluteal artery perforator flap, and two arterial thromboses in patients with TRAM flaps. Both TRAM flaps were salvaged. Delayed-immediate reconstruction is technically feasible and safe in patients with early-stage breast cancer who may require postmastectomy radiation therapy. With this approach, patients who do not require postmastectomy radiation therapy can achieve aesthetic outcomes essentially the same as those with immediate reconstruction, and patients who require postmastectomy radiation therapy can avoid the aesthetic and radiation-delivery problems that can occur after an immediate breast reconstruction.

Histologic localization of sentinel lymph node metastases in breast cancer.

Data from a recent study support the hypothesis that axillary lymph node metastases frequently localize near the inflow junction of the afferent lymphatic vessel. Our goal was to evaluate the microscopic location of axillary sentinel lymph node metastases in a prospective study of breast cancer patients. A total of 305 axillary sentinel lymph nodes from 213 breast cancer patients undergoing surgery at our institution were evaluated. Preoperative lymphoscintigraphy using technetium-labeled sulfur colloid and intraoperative isosulfan blue dye injection were used for identifying the sentinel lymph node. Intraoperatively, the surgeon placed a suture either at the point of entry of isosulfan blue dye or at the area with the highest radioactive counts, and this area was inked at the grossing bench before processing. Metastases were identified in 55 of the 305 lymph nodes examined. Thirty-four nodes contained metastases in both the inked half and the opposite half. Metastatic tumor was identified in the inked half alone in 18 lymph nodes. Only three nodes contained metastatic tumor in the opposite half with no tumor in the inked half (p <0.001). Similar results were found when nodes tagged at the point of blue dye entry and nodes tagged at the area with the highest radioactive counts were analyzed separately. Our findings suggest that metastatic tumor has a higher probability of being present in the region of the inflow junction of the afferent lymphatic vessel. This information may be useful in determining the optimal method for evaluating axillary sentinel lymph node specimens from breast cancer patients.

Clinicopathologic factors predicting involvement of nonsentinel axillary nodes in women with breast cancer.

BACKGROUND: It is unclear which breast cancer patients with positive sentinel lymph nodes (SLNs) require a completion axillary lymph node dissection. Our aim was to determine factors that predict involvement of nonsentinel axillary nodes (NSLNs) in patients with positive SLNs. METHODS: We reviewed the records of all patients with invasive breast cancer who underwent SLN biopsy at our institution between 1993 and August 2001. Multivariate analysis was used to identify clinicopathologic features in SLN-positive patients that predict involvement of NSLNs. RESULTS: A total of 131 patients had a positive SLN and underwent completion axillary lymph node dissection. Multivariate analysis revealed that primary tumor >2 cm (P =.009), SLN metastasis >2 mm (P =.024), and lymphovascular invasion (P =.028) were independent predictors of positive NSLNs. The number of SLNs harvested was a significant negative predictor (P =.04). In our model, based on the presence of these factors, the positive predictive value was 100% for a score of 4. CONCLUSIONS: The likelihood of positive NSLNs correlates with primary tumor size, size of the largest SLN metastasis, and presence of lymphovascular invasion. A scoring system incorporating these factors may help determine which patients would benefit from additional axillary surgery.

Breast-conservation therapy in early-stage breast cancer patients with a positive family history.

BACKGROUND: Our goal was to evaluate the role of breast-conservation therapy in early-stage breast cancer patients with a family history (FH) of breast cancer. METHODS: Between 1970 and 1994, 1324 female patients with breast cancer were treated with breast-conservation therapy at our institution. From these, we identified 985 patients with stage 0-II breast cancer and who had available information on FH status. FH was considered positive in any patient who had a relative who had been previously diagnosed with breast cancer. Disease-specific survival was calculated from the date of initial diagnosis using the Kaplan-Meier method. RESULTS: The stage distribution for the 985 patients was as follows: 0 in 65 (7%), I in 500 (51%), and II in 420 (43%). The median age was 50 years (range, 21-88), with a median follow-up time of 8.8 years (range,.25-29). The median tumor size was 1.5 cm. FH was positive in 31%. There were no significant differences in locoregional recurrence, distant recurrence, disease-specific survival, or incidence of contralateral breast cancer in patients with a positive FH versus patients with a negative FH. CONCLUSIONS: Breast-conservation therapy is not contraindicated in early-stage breast cancer patients with a positive FH.

Treatment and outcome of patients with intracystic papillary carcinoma of the breast.

BACKGROUND: Intracystic papillary carcinoma (IPC) of the breast is a rare form of noninvasive breast cancer. An appreciation of associated pathology with IPC may be critical in surgical decision-making. METHODS: The medical records of all patients with IPC treated between 1985 and 2001 were retrospectively reviewed. Three patient groups were identified according to the pathologic features of the primary tumor: IPC alone, IPC with associated ductal carcinoma in situ (DCIS), and IPC with associated invasion with or without DCIS. Types of treatment and outcomes were compared between groups. RESULTS: Forty patients were treated for IPC during the study period. Fourteen had pure IPC, 13 had IPC with DCIS, and 13 had IPC with invasion. The incidence of recurrence and the likelihood of dying of IPC did not differ between the three groups regardless of the type of surgery (mastectomy or segmental mastectomy) performed and whether radiation therapy was administered. The disease-specific survival rate was 100%. CONCLUSIONS: When IPC is identified, it is frequently associated with DCIS and or invasion. Standard therapy should be based on associated pathology. The role of radiation therapy in pure IPC remains to be determined.

Radiofrequency ablation of early-stage invasive breast tumors: an overview.

As the management of breast cancer evolves toward less invasive treatments, the next step is the possibility of removing the primary tumor without surgery. The most promising of the noninvasive ablation techniques is radiofrequency ablation, which uses frictional heating that is caused when ions in the tissue attempt to follow the changing directions of a high-frequency alternating current. Three pilot studies, including an ongoing study at M.D. Anderson Cancer Center, have demonstrated that radiofrequency ablation is effective for the destruction of small primary breast cancers. The most important factorfor successful radiofrequency ablation is accuracy of the ultrasound evaluation, which is used to estimate tumor size, localize the tumor for treatment, and monitor the progress of the ablation. A study in preparation at M.D. Anderson will determine whether the use of radiofrequency ablation alone for the local treatment of primary breast cancer will result in outcomes equivalent to those obtained with breast conservation therapy.
