Background. Despite well‐established surgical approaches, the prognosis for patients with squamous cell carcinoma of the esophagus remains dismal. To assess the benefit of adjuvant chemotherapy and radiation therapy (CRT), a randomized trial with and without sequential preoperative CRT was undertaken; CRT combined 20 Gy and two courses of 5‐FU and cisplatin.
Methods. Patients were included on the basis of the following criteria: squamous cell carcinoma of the esophagus, younger than 70 years of age, World Health Organization status below 2, estimated survival time greater than 3 months, and no previous treatment for the cancer. Patients were not included if they had experienced a loss in body weight greater than 15% or had tracheoesophageal fistula, metastases, or uncontrollable infection.
Results. Eighty‐six patients thus fulfilled the criteria for inclusion (41 CRT, 45 non‐CRT). The groups were well‐matched for age, sex, tumor location, size, and grade. Operative mortality was 8.5% and 7%, respectively, for each group with a 27‐day hospital stay for both groups. Long‐term survival was not significantly different, with 47% of both groups alive at 1 year.
Conclusions. The authors concluded that this neoadjuvant treatment did not change operative mortality or survival time for patients with squamous cell carcinoma of the esophagus.
Although rare, malignant transformation of intracranial epithelial cysts has a poor prognosis and surgery followed by radiotherapy seems to be the best therapeutic modality.
Oral NVB at this schedule is an effective and well-tolerated agent in the treatment of ABC and offers a promising alternative to the intravenous route. Combination studies are ongoing.
Summary This phase II study determined response rate of patients with locally advanced or metastatic head and neck cancer treated with pemetrexed disodium, a new multitargeted antifolate that inhibits thymidylate synthase, dihydrofolate reductase and glycinamide ribonucleotide formyl transferase. 35 patients with local or metastatic relapse of squamous cell carcinoma of the head and neck (31 male, 4 female; median age 53 years) were treated with pemetrexed 500 mg m 2 administered as a 10-minute infusion on day 1 of a 21-day cycle. Patients received 1 to 8 cycles of therapy. 9 patients (26.5%) had an objective response, with a median response duration of 5.6 months (range 2.9-20 months). 15 (44.1%) had stable disease, and 8 (23.5%) had progressive disease. 2 patients were not assessable for response. Median overall survival was 6.4 months (range 0.7-28.1 months; 95% CI: 3.9-7.7 months). 24 patients (68.6%) experienced grade 3/4 neutropenia, with febrile neutropenia in 4 (11.4%). Grade 3/4 anaemia and thrombocytopenia occurred in 11 (34.3%) and 6 (17.1%) patients, respectively. The most frequent non-haematological toxicity was grade 3/4 mucositis (17.1%; 6 patients). In conclusion, pemetrexed is active in squamous cell carcinoma of the head and neck. Although substantial haematological toxicities were experienced by patients, subsequent studies have shown that these toxicities can be proactively managed by folic acid and vitamin B 12 supplementation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
