The purpose of this retrospective study was to analyze the oncological follow-up of 58 patients treated for cervical CUP. Methods: From 1986 to 2006, 58 patients with cervical CUP were treated at the authors' institution. Treatment consisted of neck dissection alone in 8, irradiation or chemoradiation in 5, combined surgery and radiotherapy in 28, and surgery and radiochemotherapy in 17. Results: The 3-year and 5-year overall survival rates for all patients were 52.9% and 40.9%, respectively. The 3-year and 5-year disease-specific Survival rates were 50.9% and 39.7%, respectively. The 3-year and 5-year neck control rates were 73.7% and 67.3%, respectively. Neck dissection followed by radiochemotherapy was associated with the best 3-year and 5-year locoregional control rates. Extracapsular extension was a predictor of survival, but not of neck control. Distant metastases developed in about one third of all patients and were the most frequent cause of tumor-related death in cases of advanced neck disease.

Materials and Methods: Institutional review board approval was obtained for this retrospective study. From September 1994 to October 2008, 294 HNSCC patients were treated with adjuvant radiation and chemotherapy at the authors' department. They received normofractionated (2 Gy per fraction) irradiation to include associated nodal drainage sites, for a cumulative dose of 60-64 Gy. From January 2002 to December 2009, 91 patients received additional concomitant cisplatin-based chemotherapy. Toxicity during treatment was monitored weekly according to the common toxicity criteria (CTC); any CTC toxicity grade 3 or higher, including mucositis, dysphagia, or skin reaction, was considered high-grade acute organ toxicity. The influence of possible prognostic factors on overall survival and locoregional control was studied by means of uni- and multivariate Cox regression. Results: A statistically significant association was found between high-grade acute organ toxicity and both overall survival and locoregional control. Patients with CTC grade 3 or greater acute organ toxicity had a 5-year overall survival and locoregional control rate of 90% and 97%, respectively, as compared with 24% and 74%, respectively, in patients without such toxicity (P < .01). Multivariate analyses revealed that this association was independent from other factors that may influence treatment toxicity, especially concomitant chemotherapy and/or radiation therapy. Conclusion: The data suggest that normal tissue and tumor tissue may behave similarly with respect to treatment response, as high-grade acute organ toxicity during radiation and chemotherapy was associated with better outcomes in the patient population; therefore, the hypothesis should be further analyzed on the biomolecular and clinical level and with other tumor entities in prospective clinical trials.

Methods: Fifty-six patients with local or loco-regional recurrence of early glottic cancer were treated between 1988 and 2005 by repeated TLM followed, if necessary, by neck dissection and/or adjuvant radio- or radiochemotherapy. Data on overall survival, disease-specific survival, and loco-regional control rates were analyzed retrospectively and calculated by the Kaplan-Meier method. Results: Forty-four patients (78.6%) presented with early local recurrence (rTis-rT2N0; Stage I/II) and 12 patients (21.4%) had advanced local or loco-regional recurrence (pT3 and pT4N0/N+; Stage III/IV). Three- and five-year overall survival rates for patients with early and advanced recurrence were 75.1% vs. 51.6% and 61.6% vs. 25.8%, respectively. The corresponding three- and five-year disease-specific survival rates were 87.2% vs. 85.7% and 81.0% vs. 85.7%, respectively. Three- and five-year loco-regional control was significantly higher for patients treated for early recurrence (67.6% vs. 27.5% and 63.6% vs. 27.5%, respectively; p = 0.02).

In patients with early local recurrence, anterior commissure involvement (n = 11) did not affect the oncological results. Conclusions: In case of early local recurrence after primary TLM of early glottic cancer, further TLM seems to be justified as an organ-preserving treatment option. In contrast, salvage laryngectomy should be considered early for patients with advanced local or loco-regional recurrence. (C) 2009 Elsevier Ireland Ltd.

Methods: The records of 53 patients treated by TLM for early (rTis-rT2) and advanced (rT3, rT4) recurrence after curative radiotherapy were retrospectively analyzed. Data on loco-regional control, overall survival, and disease specific survival were calculated by the Kaplan-Meier method. The larynx preservation rates were given absolutely. Results: Mean post-therapeutic follow-up time after TLM for patients alive was 87.9 months. Twenty-two patients (42%) were cured by the first TLM procedure, but one of them underwent total laryngectomy after TLM due to chondronecrosis without evidence of residual tumor. Thirty-one patients (58%) developed another recurrence after TLM. Ten of them were cured by further laser procedures alone. Therefore, in 31 patients (58%), local recurrences were successfully treated by TLM alone. In 20 patients, recurrences could not be controlled by TLM: 14 patients underwent salvage laryngectomy and six palliative treatment. Three- and five-year loco-regional control rates for all patients were 46.1 and 38.8%. Three- and five-year overall survival rates were 67.5 and 53.3%. The corresponding 3- and 5-year disease specific survival rates were 68.6%. each. There was no statistically significant difference in loco-regional control or survival between patients presenting initially with early and advanced recurrence. Further recurrence after the first TLM procedure was associated with a statistically significant decrease in 3- and 5-year overall (56.6% vs. 81.8% and 40.2% vs. 70.5%; p = 0.03) and disease specific (48.9% vs. 100%, each; p = 0.001) survival. Ultimate local control rate including repeated TLM and salvage laryngectomy was 77.4%. Conclusions: Many patients with recurrent glottic carcinoma after primary radiotherapy can be cured by single or repeated TLM as an organ-preserving procedure. However, in case of failure after TLM for the first recurrence, salvage laryngectomy should be considered early as local control by further laser surgery is unfavorable.

Early glottic cancer can be cured with transoral laser resection, but in cases with anterior commissure involvement, there is still controversy concerning the best treatment modality. Methods. The impact of anterior commissure involvement on local control was analyzed in a retrospective review of 444 patients with early glottic cancer (pT1a-pT2a) treated between 1986 and 2004 with transoral laser microsurgical resection. Results. The anterior commissure was involved in 153 cases; the 5-year local control rate with and without anterior commissure involvement was 73% versus 89% for T1a and 68% versus 86% for T1b tumors. For T2a lesions, the 5-year local control rate was 76%, irrespective of anterior commissure involvement. Conclusion. In early glottic cancer treated by transoral laser microsurgery, a decrease in local control is evident in case of anterior commissure involvement for T1a and T1b but not for T2a tumors.
