Nine Metachronous Cancers Primarily Involving the Head and Neck: A Case Report.
Miyauchi A, et al
A remarkable case report published in Cureus describes a 62-year-old man who developed nine separate primary cancers over his lifetime, predominantly in the head and neck region, including tumors of the esophagus, gum, oropharynx, larynx, lungs, and stomach. Histopathological examination revealed a variety of cancer types, including squamous cell carcinoma, spindle cell carcinoma, mucoepidermoid carcinoma, and adenocarcinoma, highlighting the biological complexity of multiple primary malignancies in a single patient. Notably, two of the cancers—oropharyngeal and oral cancer—arose within a field that had previously been treated with radiation therapy a decade earlier, a phenomenon known as radiation-induced secondary malignancy. Crucially, all subsequent tumors were detected at early stages thanks to rigorous, multimodal surveillance, enabling minimally invasive curative surgeries and contributing to the patient's long-term survival. This case powerfully illustrates that cancer survivors, especially those with a history of multiple primary tumors, require lifelong and vigilant monitoring, as new cancers can emerge many years after initial treatment.

Source →Matriderm® as a biological scaffold in penile resurfacing: A single-centre case series.
Crane J, et al
Researchers at Norfolk and Norwich University Hospital conducted a retrospective case series evaluating Matriderm®, a bovine-derived acellular dermal matrix, combined with split-thickness skin grafts (STSGs) for single-stage penile resurfacing in 36 patients over eight years. The study addressed a significant surgical challenge, as traditional resurfacing methods often result in graft failure, contracture, and the need for multiple operations in patients affected by conditions such as buried penis syndrome, Fournier's gangrene, and cancer-related complications. Results were encouraging: successful graft uptake was achieved in 92.1% of procedures, with good-to-excellent cosmetic outcomes in 74.4% of cases and improvements in urinary and erectile function in 97% of patients with available data. Psychological outcomes, where recorded, also showed improvement in three-quarters of cases, with patients reporting better self-esteem and body image. The findings suggest that Matriderm® combined with STSG is a feasible and effective single-stage alternative to more complex multi-stage procedures, potentially reducing recovery time and improving quality of life for patients requiring penile resurfacing. The authors recommend larger prospective studies to confirm these results and evaluate long-term outcomes.

Source →Water pollution and childhood leukaemia risk: a systematic review.
Nuñez-Enriquez JC, et al
A systematic review published in Ecancermedicalscience investigated whether exposure to toxic metals and pesticides in drinking water is associated with an increased risk of childhood leukaemia, analysing observational studies published between 2001 and 2024 and identified through PubMed, Scopus, and Google Scholar. The review focused on children and young people under 20 years old diagnosed with acute lymphoblastic leukaemia or acute myeloid leukaemia, with particular attention to contaminants such as arsenic, hexavalent chromium, pentachlorophenol, and various pesticides found in drinking water sources. Results were heterogeneous: several studies suggested potential links between specific waterborne contaminants and elevated leukaemia risk in children, while others reported no significant associations and highlighted methodological limitations including small sample sizes and difficulties in accurately measuring individual exposure. Although a definitive causal relationship cannot yet be established, children are recognised as especially vulnerable due to their developing physiology and proportionally higher water intake relative to body weight. The authors conclude that current evidence remains inconclusive and call for rigorous, long-term research to clarify how waterborne pollutants may contribute to childhood leukaemia and to guide public health policies aimed at protecting child health globally.

Source →Rethinking Local Cancer Overscreening in Japan: A Path toward Organized Screening.
Minamitani M
A new commentary published in JMA Journal examines the problem of cancer overscreening in Japan, where local governments and workplaces have long offered screening tests that go beyond national evidence-based guidelines in terms of age ranges, testing intervals, and methods used. The authors argue that this administrative flexibility, while improving access, has led to the widespread use of unproven or low-value screening tools without adequate quality assurance. In 2024, Miyazaki City undertook a systematic review of its cancer screening program under new medical leadership, identifying multiple deviations from national guidelines and subsequently discontinuing non-evidence-based tests including the ABC method for gastric cancer detection, breast ultrasound screening, and prostate-specific antigen testing. This reform effort illustrates how local leadership can successfully realign community screening practices with scientific evidence even within complex institutional environments. The case highlights the broader importance of sustained collaboration among policymakers, healthcare providers, and citizens to ensure that cancer screening programs deliver genuine benefit rather than simply expanding the volume of tests performed.

Source →Adenoid Cystic Carcinoma of the Bartholin Gland: A Case Report.
Bombon MF, et al
Researchers present a case report of adenoid cystic carcinoma of the Bartholin gland, an extremely rare malignant tumor arising in the female genital tract. A 30-year-old woman with a history of Barrett's esophagus experienced months of moderate pain and localized itching in the right vulvar region before receiving her diagnosis. She underwent right hemivulvectomy combined with inguinal lymphadenectomy, and histopathological analysis confirmed the diagnosis of adenoid cystic carcinoma of the Bartholin gland. The case highlights that this condition has no established consensus treatment protocol, making surgical removal the current gold standard despite ongoing controversy. Clinicians are reminded that accurate diagnosis depends on integrating clinical findings, imaging, and histopathological evaluation. This report contributes to the limited literature on this rare pathology and underscores the need for further research to develop standardized treatment guidelines.
