Background: Few studies have demonstrated the utility of pharyngeal interposition graft (PIG) applying pectoralis major myocutaneous flap (PMMCF) by comparing pharyngocutaneous fistula (PCF) rates. Objective: The objective of this retrospective study was to clarify the utility of PIG applying PMMCF in reducing post-operative complications due to salvage total laryngectomy (STL). Material and methods: STL was performed in 59 patients with recurrent laryngeal cancer after radiotherapy, comprising 37 non-PMMCF patients and 22 PMMCF patients. The primary endpoint was PCF rate. Comparisons were made between two groups: a group with simple closure not using PMMCF (non-PMMCF group), and the other with PMMCF used in a PIG (PMMCF group). Results: PCF occurred in 15 of the 59 subjects (25.4%), including 13 of the 37 patients in the non-PMMCF group (35.1%) and 2 of the 22 patients in the PMMCF group (9.1%). PCF rate was significantly lower in the PMMCF group than in the non-PMMCF group (p = .033). Conclusions and significance: We demonstrated that PIG applying PMMCF significantly reduced the PCF rate due to STL. In the future, surgeons need to conduct research focused on additional innovations to reduce post-operative complications as much as possible. [ABSTRACT FROM AUTHOR]

Background: Salvage surgery for laryngeal cancer recurring after radiotherapy is difficult and complications readily occur. Our institution has adopted the pharyngeal interposition graft (PIG) using a pectoralis major myocutaneous (PMMC) flap, which has copious blood flow, for preventing post-irradiation pharyngocutaneous fistula. Aims/objectives: The purpose of this study was to examine the incidence of post-operative complications of salvage total laryngectomy (STL) using the PMMC flap for post-radiotherapy recurrent laryngeal cancer at our institution. Material and methods: From among 162 patients with laryngeal cancer who had been treated at Tokyo Medical University Hospital between January 2014 and March 2018, we enrolled 11 patients who had undergone STL applying a PMMC flap. We examined patient backgrounds (age, gender, subtype, stage), initial therapy (radiotherapy/chemoradiotherapy), radiation dose, irradiation area, surgery type (with/without neck dissection) and postoperative complications. Results: No severe systemic complications were encountered. Pharyngocutaneous fistula occurred as a severe local complication in one patient (8.3%) and wound infection as a mild local complication in one patient (8.3%). Conclusions: Rates of post-operative complications following STL tended to be lower at our institution than those reported for other institutions. Significance: PIG may be a useful surgical procedure in STL. [ABSTRACT FROM AUTHOR]

Background: Combination therapy consisting of a platinum agent, 5-fluorouracil and cetuximab (EXTREME regimen) is recommended for recurrent or metastatic squamous cell carcinoma of the head and neck (R/M-SCCHN). However, it is advisable to use platinum-free regimens as first-line therapy in patients resistant to platinum agents. There has been no report comparing EXTREME regimen outcomes between platinum-resistant and platinum-sensitive patients. Objectives: We conducted this study to examine the outcomes of the EXTREME regimen as first-line therapy in patients with R/M-SCCHN and a history of platinum agent use and assess whether the EXTREME regimen outcomes differ between platinum-resistant and platinum-sensitive patients. Materials and methods: The study included 32 patients with R/M-SCCHN who received the EXTREME regimen as first-line therapy. Patients with recurrence or metastasis within 6 months after cisplatin administration were considered platinum-resistant and those with no recurrence or metastasis within 6 months were considered platinum-sensitive. Results: 17 patients were platinum-resistant and 15 patients were platinum-sensitive. The median survival durations were 10.6 and 19.9 months in the platinum-resistant and platinum-sensitive patients, respectively, and the prognosis was significantly better in the platinum-sensitive patients (p ¼ .02). Conclusions: Our findings suggest that the EXTREME regimen is useful as first-line therapy for R/MSCCHN in platinum-sensitive patients. [ABSTRACT FROM AUTHOR]

Background: We devised an advanced pectoral flap (APF) to prevent anastomotic leak after total pharyngolaryngectomy (TPL) and free jejunal reconstruction (FJR) in patients with hypopharyngeal or laryngeal carcinoma. The APF alleviates tension on the skin in the neck, reduces the subcutaneous dead space, and promotes adhesion between the neck skin and the anastomosis. Objective: To investigate whether an APF is effective for prevention of anastomotic leak associated with TPL/FJR. Patients and methods: Anastomotic leak was compared between APF (n=65) and non-APF groups (n=25). Patients who had received preoperative radiotherapy or undergone tracheostomy or skin infiltration requiring neck reconstruction using a pedicle flap were excluded. Results: There were significantly fewer cases of anastomotic leak in the APF group than in the non- APF group (1.5% [1/65] vs. 16.0% [4/25]; p=.02). An APF could be created bilaterally within approximately 15 minutes. Unlike a deltopectoral flap, an APF does not require a skin graft. Conclusions: The postoperative anastomotic leak rate was 1.5% in patients who underwent TPL and FJR for hypopharyngeal or laryngeal carcinoma with an APF. Significance: An APF is easily created and can reduce the incidence of anastomotic leak after TPL and FJR. [ABSTRACT FROM AUTHOR]
