RESUMEN
PURPOSE: Induction chemotherapy with Taxotere, cisplatin, and 5-fluororacil (TPF) was mainly used in hypopharyngeal and laryngeal cancer patients for larynx preservation. This study aimed to assess feasibility and toxicity in oral cavity and maxillary sinus cancer patients. PATIENTS AND METHODS: Between 2003 and 2008, 21 patients (18 male, three female; mean age 58 years; 15 patients Eastern Cooperative Oncology Group > or =1) suffering from advanced squamous cell cancers of the oral cavity (seven primaries, eight locoregional recurrences) and the maxillary sinus (six patients) were prospectively treated with three cycles of TPF (q3w) and were scheduled to undergo definitive chemoradiation. RESULTS: Of 21 patients, 15 (71%) could be treated with all three cycles, one patient with two cycles, and five patients with one cycle. Reasons for incomplete treatment were tumor progression, edema, seizure, bad general condition, sepsis, pneumonia (each once). The infections led to two treatment-related deaths (9.5%). Acute grade III/IV side effects were noted maximally in 11 patients (52%). Main toxicities were afebrile leukopenias and neutropenias and stomatitis. Of 15 patients, six and four patients had a clinical complete or partial remission following three cycles (67%); five patients with recurrences had no response. Ten patients underwent a definitive chemoradiation or radiation (47.6%). After a mean observation time of 17 months, nine patients are alive; one of them developed a local recurrence. CONCLUSIONS: Chemotherapy with TPF is a highly effective treatment with considerable toxicity that needs special expertise which is best assured in a multidisciplinary setting. Pretreated recurrent cancers demonstrated bad response. A target for organ preservation could be the maxillary sinus; due to tumor regression in advanced oral tongue cancer, consecutively, a reduced function has to be encountered.

OBJECTIVE: This study was undertaken to assess the prognostic factors for the management of squamous cell carcinoma (SCC) of the maxillary sinus, who received preoperative chemotherapy and radiation therapy (RT). We also elucidated the appropriate sequence of chemotherapy. METHODS: A total of 124 patients (median age 62 years) with SCC of the maxillary sinus were analysed retrospectively. T3 or T4 disease was found in 93% of the patients. Thirty-nine patients received neoadjuvant chemotherapy (NA), 38 patients received concurrent chemoradiotherapy (CRT) and 47 patients received NA followed by CRT. The median dose of RT was 60 Gy. Maxillectomy was undertaken in 98 patients. RESULTS: The 5 year overall survival (OAS) and local control probability (LCP) were 56.6 and 73.7%, respectively. On univariate analysis, surgery (P < 0.0001) and T classification (P < 0.04) were significant prognostic factors for OAS and LCP. Histological grade and nodal status were also related to OAS. However, any chemotherapy sequence was not associated with the treatment outcome. On multivariate analysis, surgery (P < 0.0005) and T classification (P < 0.05) were identified as significant prognostic factors for LCP and OAS. CONCLUSIONS: This study suggests that both surgery and T stage are important prognostic factors for LCP and OAS in the management of SCC of the maxillary sinus. The appropriate sequence of chemotherapy remains to be elucidated in the future study.

BACKGROUND: The Internet has revolutionized the manner in which patients obtain information about health care. This technology has also allowed patients to obtain directly both prescription and nonprescription therapies. OBJECTIVE: To report a case of fulminant hepatorenal failure associated with the use of hydrazine sulfate, an unregulated alternative remedy for cancer marketed on the Internet. DESIGN: Case report. SETTING: Academic medical center. PATIENT: A 55-year-old man with maxillary sinus cancer. INTERVENTION: Self-medication with hydrazine sulfate. MEASUREMENTS: Serum liver and renal function tests; histologic evaluation of liver and kidney tissue. RESULTS: The patient developed hepatic encephalopathy, renal failure, and profound coagulopathy. He died after severe gastrointestinal hemorrhage developed. Autopsy revealed autolysis of the kidneys and submassive bridging necrosis of the liver. CONCLUSION: Fatal hepatorenal failure may occur after the use of hydrazine sulfate. This fatal complication must be considered in anyone taking or contemplating the use of hydrazine sulfate.

A matched-control study comparing standard radiotherapy versus neoadjuvant chemotherapy and radiation was undertaken to clarify the effects of neoadjuvant systemic chemotherapy for locally advanced squamous cell carcinoma of the maxillary antrum. Thirty-four patients with inoperable maxillary cancer were treated with neoadjuvant chemotherapy and radiotherapy (Group II). Before starting radiotherapy, all patients in Group II received two or three cycles of neoadjuvant chemotherapy consisting of cisplatin and a 5-day continuous infusion of 5-fluorouracil with or without intravenous injection of vinblastine. Radiation doses ranged from 66 Gy to 75 Gy (median, 70 Gy). The response rate, patterns of failure, toxicity, and survival for Group II were compared with those for 34 stage-matched patients treated with radiation alone (Group I). Despite a higher response rate to neoadjuvant chemotherapy, the recurrence rate and patterns of treatment failure were not influenced by the addition of neoadjuvant chemotherapy. In most cases, neoadjuvant chemotherapy did not interfere with subsequent radiotherapy, and radiation-induced late complications occurred equally in both treatment groups. After a median follow-up of 48 months, there was no significant difference in 5-year actuarial survival or disease-free survival between the two treatment groups. Radiation alone for inoperable maxillary cancer was clearly suboptimal for improving local control and survival rate, but neoadjuvant chemotherapy in addition to standard radiotherapy failed to demonstrate any therapeutic advantage over radiation alone.
