Effect of breast-conserving surgery and modified radical mastectomy on operation index, symptom checklist-90 score and prognosis in patients with early breast cancer.

The present study aims to analyze the effects of breast-conserving surgery and modified radical mastectomy on operation indexes, Symptom checklist-90 scores and prognosis in patients with early breast cancer.The clinical data of 128 patients with breast cancer who were treated in our hospital from May 2015 to May 2016 were included into the analysis. These patients were divided into 2 groups, according to the different modes of operation (n = 64): control group, patients underwent modified radical mastectomy; observation group, patients underwent early breast conserving surgery. Then, the surgical indexes and prognosis were compared between these 2 groups.Intraoperative bleeding volume, incision length and hospitalization duration were better in the observation group than in the control group (P < .05). Furthermore, postoperative symptom checklist-90 scores in the observation group were better than scores before the operation, and were better than the scores in the control group (P < .05). Moreover, the incidence of postoperative complications was lower in the observation group (3.13%) than in the control group (21.88%, P < .05).Early breast-conserving surgery is more advantageous for breast cancers and results to lesser bleeding, rapid recovery, and fewer complications.

Survival Analysis of Patients with Breast Cancer Undergoing a Modified Radical Mastectomy With or Without a Thoracic Paravertebral Block: a 5-Year Follow-up of a Randomized Controlled Trial.

AIM: This 5-year prospective follow-up of women randomized to general anesthesia (GA) with or without a thoracic paravertebral block (TPVB) examined the risk of local recurrence, metastasis and mortality after breast cancer surgery. PATIENTS AND METHODS: A total of 180 patients undergoing modified radical mastectomy were randomized to one of three study groups: standardized GA only; GA with a single-injection TPVB (s-TPVB) and placebo paravertebral infusion after surgery for 72-h; and GA plus with continuous TPVB (c-TPVB) for 72-h postoperatively. Cox proportional models were used to assess the effect of TPVB on long-term outcomes. Equivalence testing was used to help interpret the results. RESULTS: The incidence [95% confidence interval (CI)] of cancer recurrence, metastatic spread and all-cause mortality was 2.3% (0.7-5.4%), 7.9% (4.6-12.6%) and 6.8% (3.6-11.2%), respectively. Four women had cancer recurrence and had metastatic spread. Compared to the GA-only group, the risk of metastatic spread was not different from that of GA with s-TPVB [hazard ratio (HR)=1.11, 95% CI=0.32-3.83) nor from that with GA plus c-TPVB (HR=0.79, 95% CI=0.21-2.96) (p=0.88). Compared to the GA-only group, the risk of mortality was similarly not different from that of the two other groups (HR=2.57, 95% CI=0.66-9.92; and HR=0.66, 95% CI=0.11-3.97, respectively, p=0.15). CONCLUSION: Although the original study was underpowered to properly address long-term outcomes, the results of this analysis suggest that TPVB, administered whether as a single-injection or continuous infusion during the perioperative period, had little to no appreciable effect on local recurrence, metastasis or mortality after breast cancer surgery.

Contemporary operative management of T4 breast cancer.

BACKGROUND: Guidelines advise modified radical mastectomy following neoadjuvant systemic therapy for T4 breast cancer. We studied the influence of current systemic therapy and tumor subtype on pathologic stage and practice patterns to identify patients for whom less aggressive operative treatment might be considered. METHODS: We identified 98 clinical T4 M0 cases operated on at our institution from October 2008-July 2015. Patient, tumor, and treatment variables were analyzed. RESULTS: Clinical T4 substage was 7% T4a, 32% T4b, 3% T4c, and 58% T4d. Tumor biologic subtype was 41% ER+/HER2-, 36% HER2+, and 23% ER-/HER2-. A total of 86 patients (88%) had neoadjuvant systemic therapy; 87% of patients underwent total mastectomy, 9% skin-sparing mastectomy, and 4% breast conservation. Axillary dissection was performed in 74% of patients and sentinel node surgery with (14%) or without (11%) axillary dissection in the remainder; 41/98 (42%) were lymph node negative at operation. The pathologic complete response rate in the breast (31%) and axilla (39%, cN+ cases) correlated with biologic subtype (P < .0001). Overall 5-year, disease-free, and breast cancer-specific survival were 68% and 86%. CONCLUSION: Alignment with guidelines was substantial for both breast and axillary operation. Favorable breast cancer-specific survival suggests current multidisciplinary treatment has improved outcomes. Careful assessment of pathology and treatment response may identify clinical T4 patients appropriate for breast or axillary conservation.

The tumor-to-breast volume ratio (TBR) predicts cancer-specific survival in breast cancer patients who underwent modified radical mastectomy.

Breast cancer is the most common cancer in women globally, and tumor size measured as the largest diameter of the tumor focus is currently used in tumor-lymph node-metastasis (TNM) staging for prognosis and treatment decisions. The present study utilized the tumor-to-breast volume ratio (TBR) to evaluate the relative tumor size and determined the prognostic impact of TBR on survival in patients with breast cancer. Two thousand twenty-five consecutive breast cancer patients who underwent modified radical mastectomy between January 2002 and December 2008 at Sun Yat-Sen University Cancer Center were enrolled in this retrospective study. Kaplan-Meier analysis was used to assess the prognostic effect of TBR on cancer-specific survival (CSS), and univariate log-rank test and multivariate Cox proportional hazards regression model were performed to identify independent prognostic factors. The optimal cutoff value of TBR was determined to be 1.70 %, and 1473 and 552 patients were categorized to low-TBR and high-TBR groups, respectively. In the whole patient cohort, CSS was significantly shorter in the high-TBR group (110.2 vs 128.5 months, P < 0.001). Univariate and multivariate analyses revealed that TBR was an independent prognostic factor of CSS in breast cancer patients (hazard ratio (HR) 1.489, 95 % CI 1.130-1.961, P = 0.005). High TBR was independently associated with poor prognosis in breast cancer patients. This variable may serve as a valuable parameter to predict the outcomes of breast cancer.

Overall Survival, Disease-Free Survival, Local Recurrence, and Nipple-Areolar Recurrence in the Setting of Nipple-Sparing Mastectomy: A Meta-Analysis and Systematic Review.

BACKGROUND: Nipple-sparing mastectomy (NSM) is an increasingly common procedure; however, concerns exist regarding its oncological safety due to the potential for residual breast tissue to harbor occult malignancy or future cancer. METHODS: A systematic literature review was performed. Studies with internal comparison arms evaluating therapeutic NSM versus skin-sparing mastectomy (SSM) and/or modified radical mastectomy (MRM) were included in a meta-analysis of overall survival (OS), disease-free survival (DFS), and local recurrence (LR). Studies lacking comparison arms were only included in the systematic review to evaluate mean OS, DFS, LR, and nipple-areolar recurrence (NAR). RESULTS: The search yielded 851 articles. Twenty studies with 5594 patients met selection criteria. The meta-analysis included eight studies with comparison arms. Seven studies that compared OS found a 3.4% risk difference between NSM and MRM/SSM, five studies that compared DFS found a 9.6% risk difference between NSM and MRM/SSM, and eight studies that compared LR found a 0.4% risk difference between NSM and MRM/SSM. Risk differences for all outcomes were not statistically significant. The systematic review included all 20 studies and evaluated OS, DFS, LR, and NAR. Studies with follow-up intervals of <3 years, 3-5 years, and >5 years had mean OS of 97.2, 97.9, and 86.8%; DFS of 93.1, 92.3, and 76.1%; LR of 5.4, 1.4, and 11.4%; and NAR of 2.1, 1.0, and 3.4%, respectively. CONCLUSIONS: This study did not detect adverse oncologic outcomes of NSM in carefully selected women with early-stage breast cancer. Use of prospective data registries, notably the Nipple-Sparing Mastectomy Registry, will add clarity to this important clinical question.

Long-term survival outcomes following internal mammary node irradiation in stage II-III breast cancer: results of a large retrospective study with 12-year follow-up.

PURPOSE: To examine the effect of internal mammary node irradiation (IMNI) on disease-free survival (DFS) and overall survival (OS) in breast cancer patients treated with modified radical mastectomy and postoperative radiation therapy. METHODS AND MATERIALS: Between 1994 and 2002, 396 patients with stage II-III breast cancer were treated with postmastectomy radiation therapy with (n=197) or without (n=199) IMNI. Patients who received neoadjuvant chemotherapy were excluded. IMNI was administered at the clinical discretion of the treating physician. Median RT dose was 50.4 Gy (range, 45.0-59.4 Gy) in 28 fractions, with inclusion of the supraclavicular fossa in 96% of patients. Adjuvant chemotherapy was administered to 99.7% of the patients and endocrine therapy to 53%. RESULTS: The median follow-up was 149 months (range, 124-202). IMNI patients had more advanced nodal stage and non-high grade tumors than those without IMNI (P<.001). Otherwise, disease and treatment characteristics were well balanced. The 10-year DFS with and without IMNI was 65% and 57%, respectively (P=.05). Multivariate analysis demonstrated that IMNI was an independent, positive predictor of DFS (hazard ratio [HR], 0.70; P=.02). Benefits of IMNI in DFS were seen most apparently in N2 patients (HR, 0.44; 95% confidence interval [CI], 0.26-0.74) and inner/central tumors (HR, 0.55; 95% CI, 0.34-0.90). The 10-year OS with and without IMNI was 72% and 66%, respectively (P=.62). The 10-year DFS and OS were 61%, and 69%, respectively. CONCLUSIONS: Internal mammary node irradiation significantly improved DFS in postmastectomy breast cancer patients. Pending long-term results from randomized trials, treatment of internal mammary nodes should be considered in postmastectomy radiation therapy.

A nomogram to predict individual prognosis in node-negative breast carcinoma.

BACKGROUND: Currently, the benefit of chemotherapy (CT) in node-negative breast carcinoma (NNBC) is discussed. The evaluation of classical clinical and histological factors is limited to assess individual outcome. A statistical model was developed to improve the prognostic accuracy of NNBC. METHODS: A total of 305 node-negative breast carcinomas who underwent surgery (+/- radiotherapy) but no adjuvant treatment were selected. Putative prognosis factors including age, tumour size, oestrogen receptor (ER), progesterone receptor (PgR), Scarff-Bloom-Richardon (SBR) grading, urokinase plasminogen activator (uPA), plasminogen activator inhibitor 1 (PAI-1) and thymidine kinase (TK) were evaluated. The developed model was internally validated using Harrell's concordance index. A prognosis index (PI) was proposed and compared with Adjuvant! Online program. RESULTS: Age (p < 0.001), pathological tumour size (pT) (p < 0.001), PgR (p = 0.02), and PAI-1 (p ≤ 0.001) were included in the Cox regression model predicting Breast cancer specific survival (BCSS) at 5-years. Internal validation revealed a concordance index of 0.71. A PI score was derived from our nomogram. The PI score was significantly associated with BCSS (hazard ratio (HR): 4.1 for intermediate, p=0.02, HR: 8.8, p < 0.001 for high group) as compared to Adjuvant! Online score (HR: 1.4, p=0.14). CONCLUSION: A nomogram can be used to predict probability survival curves for individual breast cancer patients.

Increased risk of locoregional recurrence for women with T1-2N0 triple-negative breast cancer treated with modified radical mastectomy without adjuvant radiation therapy compared with breast-conserving therapy.

PURPOSE: To evaluate the risk of locoregional recurrence (LRR) associated with locoregional treatment of women with primary breast cancer tumors negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (triple-negative breast cancer [TNBC]). PATIENTS AND METHODS: Patients diagnosed with TNBC were identified from a cancer registry in a single institution (n=768). LRR-free survival was estimated using Kaplan-Meier analysis. The Cox proportional hazards regression model was used to determine risk of LRR on the basis of locoregional management: breast-conserving therapy (BCT; ie, lumpectomy and adjuvant radiation therapy [RT]) and modified radical mastectomy (MRM) in the TNBC population and T1-2N0 subgroup. RESULTS: At a median follow-up of 7.2 years, 77 patients (10%) with TNBC developed LRR. Five-year LRR-free survival was 94%, 85%, and 87% in the BCT, MRM, and MRM + RT groups, respectively (P < .001). In multivariate analysis, MRM (compared with BCT), lymphovascular invasion and lymph node positivity were associated with increased LRR. Conversely, adjuvant chemotherapy was associated with decreased risk of LRR. For patients with T1-2N0 tumors, 5-year LRR-free survival was 96% and 90% in the BCT and MRM groups, respectively (P = .027), and MRM was the only independent prognostic factor associated with increased LRR compared with BCT (hazard ratio, 2.53; 95% CI, 1.12 to 5.75; P = .0264). CONCLUSION: Women with T1-2N0 TNBC treated with MRM without RT have a significant increased risk of LRR compared with those treated with BCT. Prospective studies are warranted to investigate the benefit of adjuvant RT after MRM in TNBC.

Sentinel-lymph-node resection compared with conventional axillary-lymph-node dissection in clinically node-negative patients with breast cancer: overall survival findings from the NSABP B-32 randomised phase 3 trial.

BACKGROUND: Sentinel-lymph-node (SLN) surgery was designed to minimise the side-effects of lymph-node surgery but still offer outcomes equivalent to axillary-lymph-node dissection (ALND). The aims of National Surgical Adjuvant Breast and Bowel Project (NSABP) trial B-32 were to establish whether SLN resection in patients with breast cancer achieves the same survival and regional control as ALND, but with fewer side-effects. METHODS: NSABP B-32 was a randomised controlled phase 3 trial done at 80 centres in Canada and the USA between May 1, 1999, and Feb 29, 2004. Women with invasive breast cancer were randomly assigned to either SLN resection plus ALND (group 1) or to SLN resection alone with ALND only if the SLNs were positive (group 2). Random assignment was done at the NSABP Biostatistical Center (Pittsburgh, PA, USA) with a biased coin minimisation approach in an allocation ratio of 1:1. Stratification variables were age at entry (≤ 49 years, ≥ 50 years), clinical tumour size (≤ 2·0 cm, 2·1-4·0 cm, ≥ 4·1 cm), and surgical plan (lumpectomy, mastectomy). SLN resection was done with a blue dye and radioactive tracer. Outcome analyses were done in patients who were assessed as having pathologically negative sentinel nodes and for whom follow-up data were available. The primary endpoint was overall survival. Analyses were done on an intention-to-treat basis. All deaths, irrespective of cause, were included. The mean time on study for the SLN-negative patients with follow-up information was 95·6 months (range 70·1-126·7). This study is registered with ClinicalTrials.gov, number NCT00003830. FINDINGS: 5611 women were randomly assigned to the treatment groups, 3989 had pathologically negative SLN. 309 deaths were reported in the 3986 SLN-negative patients with follow-up information: 140 of 1975 patients in group 1 and 169 of 2011 in group 2. Log-rank comparison of overall survival in groups 1 and 2 yielded an unadjusted hazard ratio (HR) of 1·20 (95% CI 0·96-1·50; p=0·12). 8-year Kaplan-Meier estimates for overall survival were 91·8% (95% CI 90·4-93·3) in group 1 and 90·3% (88·8-91·8) in group 2. Treatment comparisons for disease-free survival yielded an unadjusted HR of 1·05 (95% CI 0·90-1·22; p=0·54). 8-year Kaplan-Meier estimates for disease-free survival were 82·4% (80·5-84·4) in group 1 and 81·5% (79·6-83·4) in group 2. There were eight regional-node recurrences as first events in group 1 and 14 in group 2 (p=0·22). Patients are continuing follow-up for longer-term assessment of survival and regional control. The most common adverse events were allergic reactions, mostly related to the administration of the blue dye. INTERPRETATION: Overall survival, disease-free survival, and regional control were statistically equivalent between groups. When the SLN is negative, SLN surgery alone with no further ALND is an appropriate, safe, and effective therapy for breast cancer patients with clinically negative lymph nodes. FUNDING: US Public Health Service, National Cancer Institute, and Department of Health and Human Services.

Radiotherapy can decrease locoregional recurrence and increase survival in mastectomy patients with T1 to T2 breast cancer and one to three positive nodes with negative estrogen receptor and positive lymphovascular invasion status.

PURPOSE: To define a subgroup of patients at high risk of locoregional recurrence (LRR) who might be benefit from postmastectomy radiotherapy in invasive breast cancer and tumor size <5 cm with one to three involved axillary lymph nodes (T1-2 N1). METHODS AND MATERIALS: Between April 1991 and December 2005, 544 patients with T1-2 N1 invasive breast cancer were treated with modified radical mastectomy. Of the 544 patients, 383 patients (70.4%) had no radiotherapy, and 161 patients (29.6%) received radiotherapy. We retrospectively compared these two patient groups. RESULTS: With a median follow-up of 40.3 months, LRR occurred in 40 (7.4%) of 544 patients. On univariate analysis, high nuclear grade (p = 0.04), negative estrogen receptor (ER) status (p = 0.001), presence of lymphovascular invasion (LVI) (p = 0.003), and no radiotherapy (p = 0.0015) were associated with a significantly higher rate of LRR. Negative ER status (hazard ratio = 5.1) and presence of LVI (hazard ratio = 2.5) were the risk factors for LRR with statistical significance in the multivariate analysis. Radiotherapy reduced the LRR in patients with the following characteristics: age <40 years, T2 stage, high nuclear grade, negative ER status, and presence of LVI. For 41 patients with negative ER and positive LVI status, radiotherapy can reduce LRR from 10 of 25 (40%) to 2 of 16 (12.5%) and increase the 5-year overall survival from 43.7% to 87.1%. CONCLUSION: Radiotherapy can reduce LRR and increase survival in T1-2 N1 breast cancer patients with negative ER status and presence of LVI.

[The results of breast conserving treatment in breast cancer]. / Wyniki leczenia oszczedzajacego chorych na raka sutka.

UNLABELLED: The aim of the work was to assess the results of breast conserving treatment (BCT) in early breast cancer in patients treated in Lower Silesian Oncology Centre. MATERIAL AND METHODS: Analysis of data from 167 women treated between 1997 and June 2003 with BCT and adjuvant therapy was performed. RESULTS: Only in 14 patients (8.3%) failure of treatment was observed. In 7 cases (4.8%) there was local recurrence, all of them underwent mastectomy m. Patey and they are all alive without disease symptoms. In 6 women (3.6%) dissemination of cancer was observed. Death of 5 patients (3%) between 21 and 68 months from operation took place. In Cox-Mantel test only dependency between N status and dissemination (p < 0.05) was noted. Better results of treatment were connected with estrogen receptor (ER) overexpression. Our results do not differ from data published by leading oncology centers around the world.

Early ipsilateral breast tumor recurrences after breast conservation affect survival: an analysis of the National Cancer Institute randomized trial.

PURPOSE: To evaluate the effect of an ipsilateral breast tumor recurrence (IBTR) after breast-conservation therapy (BCT) on survival. METHODS AND MATERIALS: One hundred twenty-one women were randomized to BCT. Patients with an IBTR were analyzed to determine survival. Analysis was performed with Kaplan-Meier estimates, log-rank tests, and time-dependent covariate Cox models. RESULTS: At a median follow-up of 18.4 years, 27 patients had an IBTR. The median survival time after IBTR was 13.1 years. The 5-year survival rate was 91.8% (95% confidence interval [CI], 81.5-100%). The 10-year survival rate was 54.3% (95% CI, 35.8-82.6%). According to a Cox model with time-dependent covariates, the hazard ratio or relative risk of dying for those with an IBTR at <5.3 years after BCT relative to patients without an IBTR after BCT is 1.47 (95% CI, 1.02-2.12%; p = 0.04). The hazard ratio for those who relapse after 5.3 years is 0.59 (95% CI, 0.22-1.61%; p = 0.31). Age at randomization, original tumor size, and the presence of positive regional nodes at initial presentation were not found to be associated with decreased survival. CONCLUSIONS: There seems to be a significant association of early IBTR after BCT with decreased survival. Local control should be maximized.

Breast conservation therapy rates are no different in medically indigent versus insured patients with early stage breast cancer.

PURPOSE: Multiple prospective, randomized studies show that breast conservation therapy (BCT) results in survival rates equal to mastectomy (Mx) for patients with early stage breast cancer (ESBC). Nevertheless, BCT remains underused in certain areas of the nation, without clearly definable reasons. Several studies have implicated socioeconomic status as one potential cause for this disparity in BCT usage. We sought to compare BCT rates in the medically indigent versus insured patients, within the same institution. METHODS: Data from 1993 to 2000, collected from the institutional tumor registry and the hospital's claims records, were analyzed for 928 patients with ESBC (Stages 0, I, and II), treated at a single medical center. The same surgeons treated both insured and indigent patients. Patients treated by BCT or Mx were compared for age, race, stage, insurance status, access to a radiation therapy center, surgeon, and year of diagnosis. RESULTS: Patient age, race, surgeon, or insurance status did not significantly affect the rate of mastectomy. Stage I patients (P < 0.001) and those treated after 1995 had higher BCT rates (54.9% in 1993-95 vs. 70.7% in 1996-2000; P < 0.001). Travel distance to a radiation therapy center had no significant impact on BCT rates, except for patients >40 miles distant. CONCLUSIONS: These data refute the hypothesis that socioeconomic status, as reflected by medical insurance, is a determinant of BCT in women with ESBC. Distance of <40 miles to a radiation therapy facility, Stage I disease, and diagnosis after 1995 were factors associated with higher BCT rates.

Breast-conserving therapy versus modified radical mastectomy in the treatment of early breast cancer in Japan.

BACKGROUND: Breast-conserving therapy has been widely utilized as a treatment option for women with early breast cancer. However, no randomized study comparing modified radical mastectomy and breast-conserving therapy has been conducted in Japan. METHODS: Two hundred and twenty-eight Japanese women with early breast cancer enrolled in the Gunma Breast Conserving Therapy Study between 1991 and 1994 were examined to determine whether there is any difference in disease-free survival or overall survival between radical mastectomy and breast-conserving therapy. After informed consent was obtained, a total of 119 patients underwent breast-conserving therapy and 109 underwent mastectomy. RESULTS: Mastectomy was a more frequently utilized treatment than breast-conserving therapy in patients with clinical stage II lesions, older age, larger tumor size or shorter distance between tumor and nipple. The mean follow-up period for all patients was 81 months (median 86 months). There was no significant difference in overall survival or disease-free survival between breast-conserving therapy and mastectomy even after adjusting for the clinical stage of the disease. A multivariate analysis of tumor size, lymph node status, estrogen receptor status and operation method using the Cox proportion hazard model confirmed that only lymph node status was an independent prognostic factor. CONCLUSION: Breast-conserving therapy is comparable to modified radical mastectomy in overall survival and disease-free survival.

Locoregional recurrence of breast cancer following mastectomy: always a fatal event? Results of univariate and multivariate analysis.

PURPOSE: The outcome of patients with local-regional breast cancer recurrence after mastectomy often is described as fatal. However, certain subgroups with favorable prognoses are thought to exist. To determine these favorable subgroups, we analyzed prognostic factors for their influence on postrecurrence survival by univariate and multivariate analysis. METHODS AND MATERIALS: Between 1979 and 1992, 145 patients with their first isolated locoregional recurrence of breast cancer following modified radical mastectomy without evidence of distant metastases were treated at the Department of Radiation Oncology of the University of Wurzburg. Thirty-nine percent of patients (n = 67) had had postmastectomy radiotherapy, representing 7% of patients who had received routine postmastectomy irradiation at our institution. Systemic adjuvant hormonal therapy had been applied in 24% and systemic chemotherapy in 19% of patients. Several combinations were used. Treatment of recurrences consisted of surgical tumor excision in 74%, megavoltage irradiation in 83%, additional hormonal therapy in 41%, and chemotherapy in 12% of patients, employing different combinations. Local control in the recurrent site was achieved in 86%. Median follow-up for patients alive at the time of analysis was 8.9 years after recurrence. We tested different prognostic factors, including prior treatment and treatment of recurrence, for their influence on postrecurrence survival, using univariate and multivariate analysis. RESULTS: Eighty-two of the 145 patients (57%) developed distant metastases within the follow-up period. Metastases-free rate was 42% at 2 years and 36% at 10 years following recurrence. With development of distant metastases, the survival rate deteriorated. Recurrences appeared within the first 2 years from primary surgery in 56% of patients, and in 89% within 5 years. Overall, 2-year and 5-year survival rates following local-regional recurrence were 67% and 42%, respectively. Univariate analysis revealed statistically significant worsening of survival rates for pT3 + 4 primary tumors, primary axillary lymph node involvement, tumor grading 3 + 4, lymphatic vessel invasion, blood vessel invasion, tumor necrosis, negative estrogen (ER) and progesterone (PR) hormonal receptor status, postmastectomy chemotherapy and hormonal therapy, short time to recurrence (< 1 year), combined recurrences and supraclavicular site of recurrence, non-scar recurrence, size of the largest recurrent nodule > 5 cm, multiple recurrent nodules, no surgical excision of recurrence, small target volume of irradiation, chemotherapy for recurrence, and no local control within the recurrence site. The 2-year and 5-year survival rates ranged from 68% to 94%, and from 33% to 65%, respectively, in the favorable subgroups compared to 2-year and 5-year survival rates ranging from 20% to 59% and 0% to 35%, respectively, in the unfavorable subgroups. Multivariate analysis showed that site of recurrence and number of recurrent nodules have the strongest influence on postrecurrence survival, but time to recurrence, age at time of recurrence, local control in recurrent site as well as primary pT and axillary status, and the presence of tumor necrosis in the primary tumor specimen showed additional independent influences on survival. Thus, we identified a highly favorable subgroup of patients with a single chest wall or axillary recurrent nodule (in a patient aged > 50 years), a disease-free interval of > or = 1 year, pT1-2N0 primary tumor, and without tumor necrosis, and whose recurrence is locally controlled. This group (12 patients) had 5- and 10-year survival rates of 100% and 69%, respectively. CONCLUSION: We conclude that locoregional recurrence of breast cancer following mastectomy is not always a sign of systemic disease. Our data support previous findings, that subgroups with favorable prognosis exist and they still have a chance for cure, demanding comprehensive local treatment. (ABSTR

Results of salvage mastectomy for local recurrence after breast-conserving surgery without radiation therapy.

BACKGROUND: Between 1975 and 1987, 128 patients with infiltrating breast cancer, categorized as clinical Stage I and II disease, were treated by breast conservation surgery without radiation therapy. MATERIALS: After a median disease-free interval of 20 months (range, 8-64 months), 25 of 128 patients had local recurrence, for which salvage mastectomy was performed. The results of modified radial mastectomy as a salvage procedure were analyzed in these 25 patients. RESULTS: After a median disease-free interval of 52 months (range, 8-75 years) after the salvage procedure, 12 patients had chest wall and distant recurrences, whereas 13 patients remained free of disease. The 5-year actuarial disease-free and overall survival rates after the salvage mastectomy were 51% and 65%, respectively. CONCLUSIONS: Univariate analyses of factors affecting disease-free survival and overall survival showed that the size of the local recurrence (< or = 2 cm) (P = 0.009) and the number of pathologically positive axillary nodes at the time of the salvage procedure (fewer than four nodes) (P = 0.002) were associated with a better prognosis.

Perioperative blood transfusion and survival of breast cancer patients after modified radical mastectomy.

To investigate the effect of perioperative blood transfusion on the survival of patients with breast cancer, the authors reviewed the clinical records of 455 patients who underwent modified radical mastectomy between 1960 and 1979. Thirty-eight patients (8.4%) received blood transfusions. For stage I patients who received perioperative transfusions, 5- and 10-year survival rates were 53% and 47%; for the no-transfusion group, the rates were 93% and 85%. There was also a significant difference in disease-free survival for stage I patients: for the transfusion group, 5- and 10-year survival rates were 47%; for the group not receiving a transfusion, the rates were 89% and 84%. For stage II patients, there was no difference in total or disease-free survival between those who received transfusions and those who did not, and both groups had comparable distribution of nodes.

Timing of surgery during menstrual cycle and survival of premenopausal women with operable breast cancer.

Timing of operation in relation to menstrual phase might affect outlook in premenopausal women with operable breast cancer. We examined the records of 249 such women treated between 1975 and 1985, and compared overall and recurrence-free survival in those whose operation was 3-12 days after their last menstrual period (LMP) (group 1, n = 75) with those in whom it was 0-2 or 13-32 days after LMP (group 2, n = 174). Overall and recurrence-free survival were greatly reduced in group 1 women (p less than 0.001 for both). Actuarial survival at 10 years was 54% in group 1 versus 84% in group 2. This effect was independent of other factors, was of much the same importance as nodal status in multivariate analysis, was largely confined to histologically node-positive cases, seemed to be greater in women with small tumours (less than or equal to 2 cm), and was seen in patients with oestrogen-receptor positive and negative tumours. Thus phase of menstrual cycle at operation is of great importance for long-term outlook in premenopausal women with breast cancer.

[Modified radical mastectomy--an analysis of 217 cases].

Modified radical mastectomy (MRM) was performed in two hundred and seventeen patients with operable breast cancer during 1972-1982. Having been followed for 5 to 10 years, the results were compared with those of radical mastectomy (RM) during the same period. There was no significant difference in 5 and 10 year survival rates between the two groups. MRM had the advantages of insignificant deformity, better function and easy breast reconstruction in comparison with RM. The authors believe that MRM should be recommended as the treatment of choice for breast cancer.
