MATERIALS AND METHODS: A prospective analysis of 15 patients with central retroareolar breast cancer operated from 2012 to 2018 in University Malaya Medical Center. We assessed postoperative complications, margins, locoregional recurrence, and survival outcome. All patients received postoperative radiotherapy. Patients were followed-up 1 week, 1 month, 3 monthly for 1 year and 6 monthly for 5 years.
RESULTS: Mean age of patients is 62 years. Mean follow-up is 51 months (15-84 months). All tumors were less than 5 cm (1-2.5 cm). Majority of the patients are stage 1 (6 patients/40%) and stage 2 (8 patients/ 53.3%). 2 patients had surgical site infection resolved with antibiotics. One patient had hematoma. None require reoperation. Tumor margins were clear in all patients. No locoregional recurrence. Overall survival is 100%. All are satisfied with their cosmetic outcomes.
CONCLUSIONS: Grisotti flap is a volume displacement technique, which provides satisfactory cosmetic outcome for centrally located breast cancer. This evolutionary thinking leads us to changes in existing techniques with the purpose of achieving oncological safety while reaching for better esthetic results. Our 5 years' experience in Asian population showed that this technique is oncologically safe with good cosmetic outcomes and could be used selectively. It provides a good alternative in patients who are otherwise subjected for mastectomy. This relatively simple technique is a worthwhile endeavor and should be offered when feasible.
METHODS: We assembled a large international cohort of 380 patients with relapsed iMB, age younger than 6 years, and initially treated without CSI. Univariable and multivariable Cox models of postrelapse survival (PRS) were conducted for those treated with curative intent using propensity score analyses to account for confounding factors.
RESULTS: The 3-year PRS, for 294 patients treated with curative intent, was 52.4% (95% CI, 46.4 to 58.3) with a median time to relapse from diagnosis of 11 months. Molecular subgrouping was available for 150 patients treated with curative intent, and 3-year PRS for sonic hedgehog (SHH), group 4, and group 3 were 60%, 84%, and 18% (P = .0187), respectively. In multivariable analysis, localized relapse (P = .0073), SHH molecular subgroup (P = .0103), CSI use after relapse (P = .0161), and age ≥ 36 months at initial diagnosis (P = .0494) were associated with improved survival. Most patients (73%) received salvage CSI, and although salvage chemotherapy was not significant in multivariable analysis, its use might be beneficial for a subset of children receiving salvage CSI < 35 Gy (P = .007).
CONCLUSION: A substantial proportion of patients with relapsed iMB are salvaged after initial CSI-sparing approaches. Patients with SHH subgroup, localized relapse, older age at initial diagnosis, and those receiving salvage CSI show improved PRS. Future prospective studies should investigate optimal CSI doses and the role of salvage chemotherapy in this population.
METHODS: We studied 522 patients who underwent mastectomy between 1998 and 2002 and followed them up until 2008. We defined PMLRR as recurrence to the axilla, supraclavicular nodes and or chest wall. ILR was defined as PMLRR occurring as an isolated event. Prognostic factors for locoregional recurrence were determined using the Cox proportional hazards regression model.
RESULTS: The overall PMLRR rate was 16.4%. ILR developed in 42 of 522 patients (8.0%). Within this subgroup, 25 (59.5%) remained disease free after treatment while 17 (40.5%) suffered disease progression. Univariate analyses identified race, age, size, stage, margin involvement, lymph node involvement, grade, lymphovascular invasion and ER status as probable prognostic factors for ILR. Cox regression resulted in only stage III disease and margin involvement as independent prognostic factors. The hazard of ILR was 2.5 times higher when the margins were involved compared to when they were clear (aHRR 2.5; 95% CI 1.3 to 5.0). Similarly, compared with stage I those with Stage II (aHRR 2.1; 95%CI 0.6 to 6.8) and stage III (aHRR 4.6; 95%CI 1.4 to 15.9) had worse prognosis for ILR.
CONCLUSION: Margin involvement and stage III disease were identified to be independent prognostic factors for ILR. Close follow-up of high risk patients and prompt treatment of locoregional recurrence were recommended.
