Researchers found that erlotinib is marginally cost-effective for treating patients with advanced non-small cell lung cancer, with an incremental cost-effectiveness ratio of $94,638 per life-year gained. The treatment's cost-effectiveness may be improved through targeted patient selection and biomarker-guided therapy.
A new study published in the Journal of the National Cancer Institute found that HPV vaccination benefits decline with age and frequent screening for women over 41 is likely to be low. The study suggests that newly detected HPV infections do not progress to cervical intraepithelial neoplasia grade 2 or worse, regardless of age.
US PSA screening detected fewer prostate cancers compared to a European randomized trial, with lower sensitivity being the main cause. The estimated sensitivity of PSA testing followed by biopsy was significantly lower in the US (0.26) than in the European trial (0.94).

The study found significant reductions in risk across all HPV types, paving the way for a notable decrease in cancer rates.
A new study found that men diagnosed with prostate cancer in the US face a higher risk of suicide and cardiovascular death, particularly during the first year after diagnosis. The study suggests that providing emotional counseling and support for patients newly diagnosed with cancer may be essential to mitigate this risk.
A new study found that adding a contrast agent to MRI improves the accuracy of detecting lymph node metastases. The researchers concluded that incorporating contrast enhancement in malignancy criteria improves diagnostic test accuracy, and histopathologic examination should still be used as a gold standard.
Over a two and half year period, the FDA approved 53 new oncology and hematology drugs, including 39 receiving regular approval and nine accelerated approval. Most approvals were based on single-arm, non-randomized controlled trials.

The study suggests that both perspectives are valuable for a comprehensive understanding of trea...
A new study found that smoking is associated with an increased risk of bladder cancer, which progresses over time. The study showed that even smoking fewer cigarettes per day for more years may be more harmful than smoking more cigarettes per day for fewer years.
A study published in the Journal of the National Cancer Institute found that erythropoiesis-stimulating agents increase the risk of venous thromboembolism in cancer patients. The use of these agents, approved to reduce blood transfusions during chemotherapy, may outweigh benefits due to associated risks.
Researchers found that nutlin-3 activates the p53 pathway and suppresses tumor growth in mice models of chemoresistant neuroblastoma. Oral administration of nutlin-3 as a single agent reduced tumor growth and metastasis, providing a potential treatment option for advanced-stage and chemoresistant neuroblastoma.
A new study suggests that progression-free survival (PFS) is a reasonable primary endpoint for clinical trials of metastatic cancer when the median survival post-progression (SPP) is less than 6 months. However, PFS benefit does not always translate to overall survival (OS) benefit in cases where SPP is longer than 12 months.
Primary HPV DNA screening with cytology triage is more sensitive than conventional screening for detecting cervical lesions, especially among older women. This approach can lead to fewer colposcopy referrals and follow-up tests.
Residents of the volcanic area of Mt. Etna in Catania had a more than two times higher incidence of papillary thyroid cancer compared to those elsewhere on the island. The tumors from patients in this region frequently carried the BRAF V600E gene mutation, associated with aggressive thyroid cancer.
A new study found that Jewish survivors of World War II have a higher risk of developing cancer, with increased risks observed for breast and colorectal cancer. The study, which analyzed data from over 300,000 Israeli Jews, suggests that early exposure to extreme stressors during childhood may increase cancer susceptibility later in life.
A decline in invasive breast cancer cases was observed in Spanish women starting in 2001, following a period of increasing rates from the 1980s and 1990s. The trend is attributed to screening saturation, which reduced the pool of undiagnosed prevalent cases.
