The role of adjuvant chemotherapy in stage I–III male breast cancer: a SEER-based analysis

Background and aims: Male breast cancer is an uncommon disease. The benefit of adjuvant chemotherapy in the treatment of male breast cancer patients has not been determined. The aim of this study was to explore the value of adjuvant chemotherapy in men with stage I–III breast cancer, and we hypothesized that some male patients may safely skip adjuvant chemotherapy. Methods: Male breast cancer patients between 2010 and 2015 from the Surveillance Epidemiology and End Results database were included. Univariate and multivariate Cox analyses were used to analyse the factors associated with survival. The propensity score matching method was adopted to balance baseline characteristics. Kaplan–Meier curves were used to evaluate the impacts of adjuvant chemotherapy on survival. The primary endpoint was survival. Results: We enrolled 514 patients for this study, including 257 patients treated with chemotherapy and 257 patients without. There was a significant difference in overall survival (OS) but not in breast cancer-specific survival (BCSS) between the two groups ( p < 0.001 for OS and p = 0.128 for BCSS, respectively). Compared with the non-chemotherapy group, the chemotherapy group had a higher 4-year OS rate (97.5% versus 95.2%, p < 0.001), while 4-year BCSS was similar (98% versus 98.8%, p = 0.128). The chemotherapy group had longer OS than the non-chemotherapy group among HR+, HER2–, tumour size >2 cm, lymph node-positive male breast cancer patients ( p < 0.05). Regardless of tumour size, there were no differences in OS or BCSS between the chemotherapy and non-chemotherapy cohorts for lymph node-negative patients (OS: p > 0.05, BCSS: p > 0.05). Adjuvant chemotherapy showed no signiﬁcant effects on both OS and BCSS in patients with stage I (OS: p = 0.100, BCSS: p = 0.858) and stage IIA breast cancer (OS: p > 0.05, BCSS: p > 0.05). Conclusion: For stage I and stage IIA patients, adjuvant chemotherapy could not improve OS and BCSS. Therefore, adjuvant chemotherapy might be skipped for stage I and stage IIA male breast cancer patients.

e11630 Introduction: Male breast cancer is very rare, representing only between 0.7% and 1% of all breast cancers, and only half of them are early stage cases. Objective: The present study has been designed with the aim of studying retrospectively the clinical onset and evolution of male invasive breast cancer patients (stages I and II) treated at IOHM between 1997 and 2008. Methods: The records of 3,000 breast cancer cases followed between 1997 and 2008 were searched, looking for male stage I and II breast cancer patients. A database was designed following the recommendations of the Directors of Surgical Pathology of the USA. The information registered encompassed: adjuvant treatments, recurrence date and date of final consultation or death. Results: Twelve pts were identified. Mean age (range)= 66 yo (50–89 yo). Tumoral type= Invasive Ductal Carcinoma 12 pt. Tumoral subtype= NOS 9 pt (75%) Apocrine 2 pt (17%) Micropapillar 1 pt (8%). Nottingham´s grade= Grade 2: 8 pt, Grade 3: 3 pt, N/A=1 pt. Stage= I= 6 pt, II=6 pt. ER (Positve= 9 pt, Negative=1 pt, N/A= 2 pt). PR (Positve= 8 pt, Negative= 2 pt, N/A=2 pt). Her2neu (0+= 3 pt, 1+= 3 pt, 2+= 2 pt, N/A= 4 pt). Surgery= Mastectomy= 11 pt, Lumpectomy 1= pt. Radiotherapy=5 pt. Adjuvance= No=2 pt, Hormonotherapy (HT)= 3 pt, Chemotherapy (CHT) = 3 pt, CHT+HT= 4 pt. Recurrence= Yes= 2 pt, No= 10 pt. Survival: Dead= 1 pt, Alive =11 pt. Mean Time To Progression= Stage I =66 months, Stage II =42 months. Global survival: Stage I =66 months, Stage II =52 months. Conclusions: 1. Twelve stage I and II male breast cancer patients were identified out of 3000 (0.4%) breast cancer cases diagnosed and followed in the past 10 years at the IOHM. 2. Mastectomy was the surgical procedure in 11 of the 12 cases 3. Ten pt underwent adjuvant treatment. 4. With a mean follow up time of 60 months, all stage I patients are alive and there were no recurrences. Two of the 6 stage II pts progressed and one died. No significant financial relationships to disclose.

Combination Technique

Sentinel lymph node (SLN) biopsy is the main method in staging the axilla. There are insufficient data available regarding the accuracy of an SLN biopsy in male breast cancer. The aim of this study is to evaluate whether the combination of dye and radiotracer would improve the detection rate of SLNs versus dye alone in male breast cancer patients. From February 2009 to January 2012, our SLN biopsy database was retrospectively reviewed to identify male breast cancer cases. Of the 890 SLN procedures contained in the database, 10 male breast cancer patients were identified. Patient age, body mass index, SLN biopsy technique, SLN identification, number of SLN excised, and pathology reports were reviewed. Mean age was 57.2 (34–85) years with a mean tumor size was 2.2 (1.0–4.0) cm. SLN detection ratios were two in four with blue dye and six in six with the combination technique. Overall, SLNs were identified in 8 of the 10 patients. SLN biopsy is applicable in male breast cancer cases. The addition of a radiotracer to the dye in SLN biopsy increases the detection rate of sentinel nodes in male breast cancer patients.
