ABSTRACT

OBJECTIVE: Esophageal squamous cell carcinoma (ESCC-R) is a rarely encountered sequela of chest radiation. Treatment is limited by toxicity with reirradiation and complex surgical dissection in a previously radiated field. The clinical presentation, prognosis, and treatment selection of ESCC-R remain undefined. METHODS: A retrospective review of patients with esophageal squamous cell carcinoma at a single institution between 2000 and 2017 was performed to identify patients with previous radiation therapy (≥ 5 years delay). Clinicopathologic characteristics, treatment, and outcomes of ESCC-R (n = 69) patients were compared to patients with primary esophageal squamous cell carcinoma (ESCC) (n = 827). Overall survival (OS) and cumulative incidence of recurrence (CIR) were compared using log-rank and Gray's tests, respectively. RESULTS: Median time from radiation to ESCC-R was 18.2 years. The majority of ESCC-R patients were female and presented with earlier disease and decreased behavioral risk factors. ESCC-R treated with surgery alone had worse OS than ESCC (5-year 15 vs 33%; p = 0.045). Patients with ESCC-R who received neoadjuvant treatment had higher risk of postoperative in-house mortality (16.7 vs 4.2%; p = 0.032). Patients with ESCC-R treated with surgery alone and definitive chemoradiation had higher recurrence risk than those with neoadjuvant + surgery (5-year recurrence 55 and 45 vs 15%; p = 0.101). CONCLUSION: Neoadjuvant chemotherapy or chemoradiation should be used whenever possible for ESCC-R as it is associated with lower risk of recurrence. The improved survival benefits of aggressive treatment must be weighed against the higher associated postoperative risks.

ABSTRACT

Breast cancer is the leading cause of cancer death in women younger than 40 years. Triple-negative breast cancer (TNBC) and human epidermal growth factor receptor-2 (HER2) positive subtypes have a particularly poor prognosis in this age group. The purpose of this study was to compare rates of recurrence among breast cancer subtypes in young patients treated with modern adjuvant systemic therapy. A retrospective review of breast cancer patients managed at a major academic breast center between May 2000 and November 2014 was performed. We included 239 women with breast cancer who were diagnosed and treated at age ≤40 years. Clinical, pathological, therapeutic, and outcome data were recorded. Patients were classified into the following molecular subtypes: luminal A/B (estrogen receptor [ER] positive and/or progesterone receptor [PR] positive, and HER2 negative), luminal/HER2 (ER positive and/or PR positive, and HER2 positive), HER2- enriched (ER negative, PR negative, and HER2 positive) and TNBC (ER negative, PR negative, and HER2 negative). Descriptive statistics were used to characterize the study cohort. Kaplan-Meier survival analysis was performed to estimate recurrence-free survival (RFS). Median follow-up time was 29 months. Mean age was 34.5 years. Among all patients, 193 (80.8%) were diagnosed with Invasive breast cancer and 46 (19.2%) with ductal carcinoma in situ with or without microinvasion. Subclassification into molecular subtypes was complete for 199 patients among which, 50.7% were classified as luminal A/B, 21.1% luminal/HER2, 12.1% HER2-enriched and 16.1% TNBC. Of the 199 patients, 25.1% received neo-adjuvant chemotherapy and 59.2% received adjuvant chemotherapy. Among HER2-positive patients, 81.3% received HER2 directed therapy. Twenty-eight patients (11.7%) had recurrences (13 loco-regional, seven distant, and eight both). At 3 years, the HER2 subtype had the highest RFS 100%, compared to 91.1% in luminal A/B, 85.6% in luminal/HER2 and 81.9% in TNBC. In comparing outcomes among subtypes, the HER2 positive subtype was associated with improved RFS, likely reflecting the impact of HER2 directed therapy. Those young patients with triple-negative subtype continued to have the poorest outcomes.

ABSTRACT

BACKGROUND: Nipple-sparing mastectomy (NSM) is increasingly used as an alternative to traditional mastectomy because it provides improved aesthetic results. The data on its oncologic safety are limited. The authors' institution has performed NSM during the past 10 years for both oncologic and prophylactic indications. This study aimed to examine oncologic outcomes after NSM for breast cancer. METHODS: The study retrospectively examined all NSM cases managed between July 2007 and July 2013. Descriptive statistics were used to characterize the study cohort. Kaplan-Meier survival analysis was performed to estimate recurrence-free survival, specifically the 36-month recurrence-free survival proportion. RESULTS: A total of 721 nipple-sparing mastectomies were performed for 413 patients: 45 (10.9 %) to reduce risk and 368 (89.1 %) for breast cancer. In the breast cancer group, 29.8 % of the patients had ductal carcinoma in situ, and 70.2 % had invasive cancer. The mean follow-up time was 32 months (range 0.01-90.2 months). In the breast cancer group, the Kaplan-Meier 3-year recurrence-free survival rate was 93.6 % (95 % confidence interval, 89.9-96.0 %). Eight patients (2.2 %) had locoregional recurrences, including one in the nipple. Nine patients (2.4 %) had distant recurrence, and six patients (1.6 %) had a diagnosis of both local and distant recurrences. CONCLUSIONS: The findings showed a locoregional recurrence rate of 2.2 %, with an overall recurrence rate of 6.3 % for patients undergoing NSM for the treatment of breast cancer. The majority of these recurrences were distant, with one recurrence at the nipple. These results are promising, but a longer follow-up evaluation of this cohort is necessary.
