We aimed to study the frequency and prognostic effect of low hemoglobin (Hb) level in head and neck squamous cell carcinoma (HNSCC) before radiotherapy (RT) and/or chemoradiotherapy (CRT). Material and Methods: We retrospectively studied the charts of 86 patients diagnosed with laryngeal and hypopharyngeal SCC in a university hospital in Cairo, Egypt. Based on the World Health Organization (WHO), anemia was diagnosed in males at Hb levels < 13 g/dl and <12 g/dl in females. We examined the Hb levels before radiotherapy alone or combined with chemotherapy and its impact on re-sponse to treatment and survival. Results: The median age was 56 years. 75/86 (87.2%) patients were males with performance status1 in 73/86 (84.9%) patients. The median Hb level was 13.1 g/dl. The pre-RT/CRT Hb level in female patients (n = 11) was 12 g/dl in 7/11 (63.6%) patients. Pre-RT/CRT Hb level in male patients was <13 g/dl in 31/75 (41.3%) and >13 g/dl in 44/75 (58.7%). Tumor sites were larynx in 77 (89.5%) and hypopharynx in 9 (10.5%) patients. Disease stage 3, 4 was common in 59/86 (68.6%) patients. Thirty-six (41.8%) patients had surgery. 13/86 (15.1%) patients received induction chemotherapy, while 31/86 (36.0%) had concomitant chemoradiotherapy. Radiotherapy was given in 65/86 (75.58%) patients. The mean RT dose was 66 Gy. Non-anemic patients had significant higher inci-dence of complete response (CR) to treatment (p = 0.034). 25.8% of male pa-tients with Hb < 13 g/dl had higher incidence of recurrence (p = 0.036) com-pared to recurrence in 39.5% of male patients with Hb > 13 g/dl (p = 0.403). Female patients whether anemic or non-anemic had no recurrence (p = 0.036 and p = 0.403 respectively). The median duration of DFS and OS was 6.52 and 9.33 months respectively. Pretreatment Hb level had statistical significant effect on response to treatment and overall survival, but not disease free survival. Conclusion: Nutritional anemia is common in developing countries. Our results support the positive prognostic effect of Hb level > 12 g/dl and >13 g/dl before radiation therapy and/or chemoradiotherapy on response to treatment and overall survival but not the disease free survival.展开更多

However, the best treatment is still controversial due to lack of randomized controlled trials. We aimed to evaluate the treatment results and the prognostic factors of local control of early glottic squamous cell carcinoma patients (GSCC) T1-2N0M0 treated at our institution. Material and Methods: We retrospectively studied the charts of 52 patients with early GSCC T1-T2N0M0 from 2010-2015 at the Clinical Oncology Department, Ain-Shams University. 24 patients had T1 and 28 had T2 early glottic carcinoma. The overall survival OS, local control rate, and laryngeal preservation rate were evaluated. Kaplan-Meier method, Cox proportional hazards model were used to analyze the data. Results: Median duration of follow-up was 13 months. Thirty-eight patients received radiation treatment alone (73.1%), 7.7% of the patients underwent surgery alone, and 19.2% of the patients had surgery combined with radiotherapy. Local recurrence after radiation failure developed in 6/52 patients, all had T2 disease and were salvaged by total laryngectomy. The ultimate local control rate was 88.5%, and the ultimate laryngeal preservation rate was 77.2% (40/52 patients). The median OS of the 52 patients was 13 months (range 2 - 46 months). Univariate analysis of factors associated with poor local control showed that age > 60 years was the only significant factor (P = 0.048). Conclusion: Radiotherapy achieves high local control and laryngeal preservation rates for patients with early glottic carcinoma, and is associated with a low rate of severe complications compared to surgery. Salvage surgery is feasible after radiotherapy failure.展开更多
