Differential impact of proton pump inhibitors and antibiotics on immunotherapy efficacy after chemoradiotherapy in locally advanced non-small-cell lung cancer: a post-hoc analysis of the PACIFIC trial

July 10, 2026

| Cancers, Immunotherapy & Targeted Therapies

Comment: There is a pervasive habit in oncology of treating supportive care medications as biologically inert. However, outside of the cancer clinic, the epidemiological data is already glaringly clear: proton pump inhibitors (PPIs) are not benign. Chronic PPI use is definitively linked to increased risks of chronic kidney disease, major adverse cardiovascular events, and elevated […]

Physical Health Decline After Chemotherapy or Endocrine Therapy in Breast Cancer Survivors

| Cancer - Breast, Cancers, Chemotherapy, Endocrine Therapy

Comment: This prospective cohort analysis provides a highly needed, long-term look at the structural reality of post-treatment life for breast cancer survivors. The central strength of the study is how it separates the distinct physical trajectories of cytotoxic chemotherapy from hormone-modulating endocrine therapies, balancing them against age-matched controls to account for the background baseline of […]

Vitamin D supplementation increases objective response rate and prolongs progression-free time in patients with advanced melanoma undergoing anti-PD-1 therapy

| Cancer - Melanoma, Immunotherapy & Targeted Therapies

Comment: The clinical management of advanced melanoma has been transformed by the arrival of anti-PD-1 immunotherapy, yet we frequently observe a frustrating divergence in response among patients receiving the same conventional standard-of-care. This observational cohort study of 200 patients identifies a critical metabolic requirement that likely dictates the success of these conventional treatments: serum vitamin […]

Risks of second primary cancers among 584,965 female and male breast cancer survivors in England: a 25-year retrospective cohort study

| Cancer - Breast, Cancers, Chemotherapy, Radiation Therapy

Comment: Although conventional treatments for breast cancer has made astounding improvements over the 35 years that I’ve been in the field, we have to acknowledge that along with it comes a long-term price paid by the patient’s systemic health. This study provides a definitive signal on the iatrogenic risks associated with the standard-of-care. The clinical […]

Postmastectomy radiation improves local-regional control and survival for selected patients with locally advanced breast cancer treated with neoadjuvant chemotherapy and mastectomy

January 7, 2026

| Cancer - Breast, Radiation Therapy

Comment: The primary disconnect in this data is the dramatic, nearly five-fold reduction in local-regional recurrence that fails to translate into a statistically significant overall survival benefit for the general cohort. While a 10-year local recurrence rate of 11% compared to 22% is a clear victory for regional management, the P=.063 for overall survival reminds […]

Precautions for breast cancer-related lymphoedema: risk from air travel, ipsilateral arm blood pressure measurements, skin puncture, extreme temperatures, and cellulitis

January 1, 2026

| Cancer - Breast, Mastectomy-Lumpectomy

Comment: This synthesis serves as a robust rebuttal to the long-standing “precautions” that have dominated lymphedema education. The findings demonstrate that most traditional prohibitions—specifically air travel and blood pressure measurements—are effectively myths that lack Level 1 or 2 evidence. The core tension is between a historical focus with these external triggers and the clinical reality […]

Impact of antioxidant supplementation on chemotherapeutic efficacy: a systematic review of the evidence from randomized controlled trials

December 20, 2025

| Cancers, Chemotherapy, Supplements

Comment: This systematic review serves as a definitive corrective to the long-standing dogma against concurrent antioxidant use with chemotherapy. Patients still come in being told that antioxidants might ‘rescue’ tumor cells from chemotherapy, almost completely from preclinical models. However, these findings remind us why Randomized Controlled Trials are the ultimate arbiter. When tested in actual […]

Antioxidant supplementation and breast cancer prognosis in postmenopausal women undergoing chemotherapy and radiation therapy

| Cancer - Breast, Chemotherapy, HRT - Hormone Replacement Therapy, Supplements

Comment: While the headline of this study suggests a clear danger, the methodology reveals significant issues which makes the results difficult to trust. They ‘lump’ biologically distinct agents—grouping trace minerals like selenium with high-dose Vitamin C—which renders the ‘antioxidant’ variable clinically meaningless. This is the same mistake done in this trial, which is really a […]

Perioperative NSAIDs and Long-Term Outcomes After cancer Surgery: a Systematic Review and Meta-analysis

December 14, 2025

| Cancers, Medications - General Pharmaceuticals, Treatments – Conventional

Comment: This is a weak study in numerous ways, with large heterogenicity and a significant results borne of several non-significant studies which always makes it suspect. And if a patient has no contraindications, choosing an NSAID over acetaminophen if pain control is needed seems like the clear winner. The Wonk Debate – Audio Critique & […]

Hyperglycemia and Chemoresistance in Breast Cancer: From Cellular Mechanisms to Treatment Response

December 9, 2025

| No Comments

| Cancer - Breast, Cancers, Chemotherapy

Comment: A solid, though non-systematic, review that effectively compiles preclinical evidence showing how hyperglycemia drives chemoresistance via metabolic reprogramming (the Warburg effect). Crucially, it reminds us that aggressive glycemic control is a clinically relevant intervention. The Wonk Debate – Audio Critique & Clinical Commentary: Summary: Clinical Bottom Line This narrative review synthesizes preclinical and clinical […]
