A novel hMSH2 gene mutation was found in a Chinese HNPCC kindred, associated with an increased risk of colorectal cancer in four successive generations. The mutation resulted in Asp 603 Gly of hMSH2 and was present in four out of ten family members.
A 12-year study found a significant increase in differentiated thyroid cancer cases, with small subclinical tumours accounting for the rise. Advances in medical imaging are thought to be responsible for the increased detection rate, rather than a change in disease patterns.
Researchers identified kisspeptin and GPR54 as independent prognostic biomarkers specific for ovarian clear cell carcinoma. These molecular markers are associated with a favourable prognosis and could potentially be used to monitor disease activity or as therapeutic agents in women with this subtype of ovarian cancer.
A recent study found that the tumor suppressor gene H-REV107-1 stimulates growth in non-small cell lung carcinomas via mitogenic signaling. In contrast to expected function, cytoplasmic localization of H-REV107-1 correlates with decreased patient survival.
A new study has shown that PET with 11C-Choline improves the early diagnosis of relapsed prostate cancer, with a sensitivity of 65% compared to 28% for conventional FDG. This finding is particularly useful for detecting relapses in patients with low PSA levels.
Researchers found women with invasive lobular carcinoma have a different disease type, benefiting from tailored treatment approaches. Alternative therapies like hormonal treatments may be more effective for this rare form of breast cancer.
A new study found that most phase I studies of targeted, non-cytotoxic anticancer agents used traditional toxicity endpoints to determine the recommended dose, while non-traditional endpoints were rarely incorporated. Researchers also identified a potential mechanism for acrylamide's mutagenicity and discovered genetic polymorphisms as...
Researchers found that 68% of invasive low-grade ovarian tumors and 61% of precancerous lesions carried one of the three common mutations in BRAF or KRAS. Blocking KRAS-BRAF signaling may provide more effective therapy for these cancers, which generally do not respond well to conventional chemotherapy.
A study found that herpes simplex virus-2 (HSV-2) infection may increase the risk of invasive cervical cancer, particularly when combined with human papillomavirus (HPV) infection. The study analyzed data from seven countries and detected HSV-2 antibodies in nearly half of women with cervical cancer, but not in most women without the d...
Researchers at the University of Michigan have created a new line of transgenic mice that spontaneously develop skin tumors resembling human basal cell carcinomas. The mice produce abnormally large amounts of Gli2 protein, which plays a key role in the development of these common skin tumors.
A new study uses computational tools to track human cancer development, suggesting that adenoma and carcinoma lines can arise from a common precursor but develop in parallel. This challenges the conventional model of cancer progression, which assumes a linear process from normal cell to polyp to cancer.
A new clinical trial has shown that combining chemotherapy with radiation therapy can improve the survival rate of patients with nasopharyngeal carcinoma by 31% compared to radiation alone. The treatment, which included cisplatin and 5-fluorouracil, resulted in a three-year survival rate of 76% for those receiving the combination therapy.
An international team of researchers has cloned the human gene responsible for basal cell carcinoma, a common skin cancer. The discovery could lead to novel approaches in preventing and treating the disease, including a potential ointment that controls growth.
