Objective: The objective of this study was to evaluate the results of salvage surgery after definitive chemoradiation for hypopharyngeal squamous cell carcinoma.
Methods: This was a retrospective cohort study. Of the 79 patients with previously untreated hypopharyngeal squamous cell carcinoma who received definitive chemoradiation from January 2004 to January 2009, 24 who had recurrence and underwent salvage surgery at the National Cancer Center Hospital East, Chiba, Japan, were enrolled in this study.
Results: Of the 24 patients who underwent salvage surgery with curative intent, 13 had an isolated local failure, eight had an isolated neck failure and three had combined local and regional failure. Postoperative surgical complications were observed in eight (33.3%) patients. Of the 24 patients undergoing salvage surgery, 12 (50%) had recurrence. In 11 of these patients, death ensued from salvage failure, defined as the presence of any recurrence after salvage treatment. The causes of cancer-specific death ensuing from salvage failure were regional recurrence of the tumor (n = 6) (one of whom had concurrent distant metastases) and distant metastases alone (n = 5). No local recurrence after salvage surgery was observed in our group of patients. The disease-free and overall 24-month survival rates were 49.0 and 50.0%, respectively. Those patients who initially presented with unresectable disease had lower overall survival compared with those who initially presented with resectable disease (P = 0.0003).
Conclusions: The oncologic outcomes were acceptable in those patients in whom salvage surgery was carried out. Those who initially presented with unresectable disease had a poor prognosis.

Treatment of exposed tibial bone by old school burr holes - a case report.
Acta Chir Plast
January 2025
Background: We report a successful wound treatment of a chronic ulcer with bone exposure using a somehow forgotten technique of creating burr holes into the bone. Most clinics would promote flap surgery to cover wounds with bone exposure, however, in some cases invasive surgery is not mandatory. We bring up an alternative treatment for such cases.

Non-healing soft tissue defects pose challenges to treating physicians. Microsurgical reconstruction is a treatment option for achieving wound closure and limb salvage. These free tissue transfers are often challenging due to associated risk factors.

Localized high-risk (HR) prostate cancer (PCa) is a heterogeneous disease whose likelihood of a biochemical recurrence, metastatic progression and cancer-related mortality after initial treatment is higher when compared with patients with low (LR) or intermediate-risk (IR) disease. In the past, neoadjuvant therapy has shown an improvement in postoperative oncological variables but failed to demonstrate any survival advantages. With the promising results from novel treatments in metastatic and non-metastatic castration resistant PCa settings, new evidence has appeared in the literature in the neoadjuvant setting.

Martini-Klinik Prostate Cancer Center, University Hospital Hamburg-Eppendorf, 20246 Hamburg, Germany.
Background: To examine the feasibility and safety of the SENSEI drop-in gamma probe for robot-assisted, prostate-specific membrane antigen (PSMA)-radioguided salvage surgery (RGS) in lymph node or local oligorecurrent prostate cancer (PCa), detected via PSMA positron emission tomography/computed tomography (PET/CT).
Methods: The first thirteen patients with pelvic oligorecurrent PCa who underwent [Tc]Tc-PSMA-I&S RGS using the SENSEI drop-in gamma probe at the Martini-Klinik (February-June 2024) were retrospectively analyzed. Radioactivity measurements in counts per second (CPS) as absolute values or ratios (CPS of tumor specimens/mean CPS from the patients' benign tissues) were correlated with preoperative imaging and pathological findings (benign/malignant, lesion size).

: Cancer cells rely on metabolic reprogramming that is supported by altered mitochondrial redox status and an increased demand for NAD. Over expression of Nampt, the rate-limiting enzyme of the NAD biosynthesis salvage pathway, is common in breast cancer cells, and more so in triple negative breast cancer (TNBC) cells. Targeting the salvage pathway has been pursued for cancer therapy.
