Docetaxel-Cisplatin-Fluorouracil Induction Chemotherapy for Larynx Preservation in Patients with Locally Advanced Hypopharyngeal Cancer: Predictive Factors of Oncologic and Functional Outcomes.

BACKGROUND: The aims of this study were to evaluate the clinical outcomes and their predictive factors in locally advanced hypopharyngeal cancer (HC) patients included in a docetaxel-cisplatin-fluorouracil induction chemotherapy (ICT)-based larynx preservation (LP) program. METHODS: Between 2005 and 2021, 82 patients with a locally advanced resectable HC who received ICT in an LP program were included in this retrospective study. The predictors of oncologic and swallowing outcomes were determined in univariate and multivariate analyses. RESULTS: The three- and five-year overall survival (OS) rates were 67 and 54%, respectively. The T4 tumor stage was the only predictive factor of poor response to ICT (p = 0.03). In multivariate analysis, a T stage = 4 (p = 0.02), an ICT cycle number < 3 (p = 0.003) and the absence of a response to ICT (p = 0.03) were significantly associated with worse OS. A low body mass index before therapy (p = 0.003) and enteral nutrition during therapy (p = 0.005) were significantly associated with severity of dysphagia 6 months after treatment. CONCLUSIONS: The T stage, number of ICT cycles performed and response to ICT are the main predictors of oncologic outcomes. Patients with T4 HC are poor candidates for LP and should be referred to immediate radical surgery.

Salvage vs. Primary Total Laryngectomy in Patients with Locally Advanced Laryngeal or Hypopharyngeal Carcinoma: Oncologic Outcomes and Their Predictive Factors.

BACKGROUND: The aims of this study were to compare the survival outcomes of salvage vs. primary total laryngectomy (TL) in patients with locally advanced laryngeal or hypopharyngeal carcinoma and to determine their predictive factors. METHODS: Overall (OS), cause-specific (CSS) and recurrence-free survival (RFS) of primary vs. salvage TL were compared in univariate and multivariate analysis taking into account other potential predictive factors (tumor site, tumor stage, comorbidity level etc.). RESULTS: A total of 234 patients were included in this study. Five-year OS was 53% and 25% for the primary and salvage TL groups, respectively. Multivariate analysis confirmed the independent negative impact of salvage TL on OS (p = 0.0008), CSS (p < 0.0001) and RFS (p < 0.0001). Hypopharyngeal tumor site, ASA score ≥ 3, N-stage ≥ 2a and positive surgical margins were the main other predictors of oncologic outcomes. CONCLUSIONS: Salvage TL is associated with significantly worse survival rates than primary TL highlighting the need for careful selection of patients who are candidates for larynx preservation. The predictive factors of survival outcomes identified here should be considered in the therapeutic decision-making, especially in the setting of salvage TL, given the poor prognosis of these patients.

Biomolecular Factors Represented by Bcl-2, p53, and Tumor-Infiltrating Lymphocytes Predict Response for Adjuvant Anthracycline Chemotherapy in Patients with Early Triple-Negative Breast Cancer.

Treatment of triple-negative breast cancer is challenging. Standard adjuvant tretment is considered to be the cobination of anthracycline and taxanes although the role of anthracyclines administered preoperatively  remains controversial. Actually, some studies recommended taxane-only regimens. We reviewed literatures to examine whether tissue biomarkers available in an ordinary laboratory setting (eg, haematoxylin and eosin and immunohistochemistry) may predict response to adjuvant anthracyclines in patients with triple-negative breast cancer. Our review showed that Bcl-2, p53, and tumor-infiltrating lymphocytes (TILs) expression may become independent predictors for triple-negative breast cancer. This finding was based on data from retrospective studies, and, thus, randomized controlled study is needed to confirm the present results.

Pathologic Response After Weekly Paclitaxel versus Docetaxel in Operable Breast Cancer.

INTRODUCTION: Weekly paclitaxel (Ptx) and q3w docetaxel (Dtx) are equivalent in adjuvant breast cancer treatment. Weekly Ptx is better tolerated than q3w Dtx and became the first choice in daily practice, even preoperatively. METHODS: To compare the efficacy and safety of the two regimens, a retrospective analysis was performed in breast cancer patients (pts) referred for neoadjuvant, sequential, taxane-containing chemotherapy to the Institute of Oncology and Oncofort Clinic, Bucharest, between 2008 and 2017. RESULTS: Forty-seven cases were eligible, median age was 56 years (34-73 years), mainly stage IIIA-B (53.2%, 25 pts) and ductal invasive (70.2%, 33 pts) of which 24 pts (51%) received q3w Dtx and 23 pts (48.9%) weekly Ptx. The histological response rates were 62.5% (15 pts) and 73.7% (17 pts) (p=0.47), average dose-intensity was 87.7% and 96.7% (p=0.002) and grade III-IV toxicity rate was 12.5% and 13% (p=0.64), respectively. Pathologic response was correlated with immunophenotype, PgR expression, tumor size and backbone chemotherapy (p<0.05). DISCUSSION: Our study showed an improved efficacy of taxane's weekly administration, probably due to a better tolerance and a lower rate of dose-impairing toxicities.
