BACKGROUND Concurrent chemotherapy is a well-established treatment modality for locally advanced head and neck cancer. The concept of concurrent chemotherapy and radiation was introduced in an attempt to improve the local control and possibly influence the survival because of the high rate of local and distant failures observed with the combination of surgery and postoperative radiation. The relevance of this study was to assess the efficacy of our treatment and patience compliance and also study the effect in patients treated with cisplatin based concurrent chemo radiotherapy in advanced head and neck cancer. METHODS The prospective study was conducted in the Department of Radiotherapy, Government Medical college, Thrissur, Kerala comprising the newly diagnosed patients with locally advanced head & neck cancers over one year. Conventional radiotherapy with a dose of 66 Gy in 33 fractions over 6.5 weeks was given concurrently with Inj cisplatin 100 mg / 2 IV every 3 weeks and periodically followed up for one year. RESULTS This study revealed that complete response rate was higher in 61 – 70 year age group compared to lower age groups. Complete response cases were slightly higher in T1 disease compared to higher stages. Regarding nodal status, complete response and DFS were more in N0 tumours and worst in N3 tumours. It was found that complete response rates were slightly higher in stage III than stage IV. Comparing the grade of the tumour, complete response cases were slightly higher in WD and MD compared to PD. Complete response rate and disease free survival (DFS) were slightly higher in cases who had more than two chemotherapy cycles compared to one cycle. CONCLUSIONS Concurrent chemo radiation was not well tolerated in our study group. Only 23.5 % patients were able to complete the planned treatment. The positive side was that complete response was found in about 79.4 % of study patients & DFS at one year was 80 %. KEY WORDS Concurrent Chemo Radiation, Head and Neck Cancer, Cisplatin

PURPOSE To determine whether the addition of infusional fluorouracil (I-FU) to standard radiotherapy improves survival at acceptable toxicity in patients with locally advanced squamous cell head and neck cancer (SCHNC). PATIENTS AND METHODS Consenting patients with an Eastern Cooperative Oncology Group (ECOG) performance status < or = 2; with stage III or IV SCHNC of the oral cavity, oropharynx, hypopharynx, or larynx; and who were recommended for radiotherapy with curative intent received 66 Gy of radiation therapy delivered in 2-Gy fractions once daily 5 days per week for 6 1/2 weeks. Those in the experimental arm received I-FU 1.2 g/m2/d, as a 72-hour infusion in the first and third weeks of radiation. Saline infusions were used in the placebo arm. RESULTS One hundred seventy-five patients were randomized (88 to I-FU and 87 to placebo), and the treatment arms were well balanced. The complete response rate was 68% for I-FU and 56% for placebo (P = .04). The overall median survival duration was 33 months for I-FU and 25 months for placebo (P = .08). Progression-free survival also favored I-FU (P = .06). Toxicity was greater in I-FU patients, but did not interfere with the scheduled delivery or completion of radiation. CONCLUSION The addition of I-FU to standard radiation in SCHNC improved the complete response rate and was associated with beneficial trends in progression-free and overall survival compared with radiation alone. I-FU patients also experienced greater morbidity, but this did not compromise delivery of radiotherapy.

6064 Background: An oral fluoropyrimidine, S-1, has shown high efficacy against head and neck cancer (HNC) with a response rate of 34% and preclinical data has demonstrated a possible synergy with platinums and taxanes. The aim of this study was to determine the maximum tolerated dose (MTD) of a combination therapy with TPS in patients (pts) with locally advanced or recurrent/ metastatic HNC. Methods: The eligibility criteria were: histologically proven squamous cell carcinoma of the head and neck with recurrent/metastatic and locally advanced lesions, PS 0–1, age =75 years, adequate organ function, and no prior chemotherapy. Chemotherapy consisted of 1-hour infusion of docetaxel at escalating doses of 50 and 60 mg/m2, 2-hour infusions of cisplatin at 70 mg/m2/day on day 1 and S-1 twice daily on days 1–14 at escalating doses of 40, 60, and 80 mg/m2/day. The treatment was repeated every 4-weeks. Results: Twenty two pts were enrolled. These were 17 males and 5 females with a median age of 50 years (22–74). There were 11 locally advanced and 11 metastatic cases. Median of 3 cycles were administrated (range 1–6; total 77 cycles). Anorexia, nausea, neutropenia and anemia were the most frequently observed adverse events. Grade 3 or 4 hematological toxicities were neutropenia (59%), febrile neutropenia (0%), anemia (14%) and thrombocytopenia (0%). Although a total of 12 pts were treated with TPS at doses of 60/70/80 mg/m2/day, one-dose limiting toxicity (grade3 infection) was observed at these doses, but MTD was not reached. As the approved dose of S-1 is 80 mg/m2, further dose escalation was not conducted. In a total of 22 pts treated with the TPS, 3 (1 locally advanced, 2 metastatic cases) achieved complete response and 11 (7 locally advanced, 4 metastatic cases) achieved partial response according to RECIST with an overall response rate of 64%. Conclusions: The TPS combination was well tolerated in pts with locally advanced or recurrent/ metastatic HNC. Although MTD was not reached and the data were preliminary, the antitumor activity was very promising, and this warrants further investigation. No significant financial relationships to disclose.

Abstract Background To examine the effect of prior use of cetuximab and neck dissection on the effectiveness of nivolumab, we conducted a large-scale subgroup analysis in Japanese patients with recurrent/metastatic head and neck cancer. Methods Data on the effectiveness of nivolumab were extracted from patient medical records. All patients were analyzed for effectiveness by prior cetuximab use. In the analyses for prior neck dissection, only patients with locally advanced disease were included. Results Of 256 patients analyzed, 155 had received prior cetuximab. Nineteen of 50 patients with local recurrence underwent neck dissection. The objective response rate was 14.7 vs 17.2% (p = 0.6116), median progression-free survival was 2.0 vs 3.1 months (p = 0.0261), and median overall survival was 8.4 vs 12 months (p = 0.0548) with vs without prior cetuximab use, respectively. The objective response rate was 23.1 vs 25.9% (p = 0.8455), median progression-free survival was 1.8 vs 3.0 months (p = 0.6650), and median overall survival was 9.1 vs 9.9 months (p = 0.5289) with vs without neck dissection, respectively. Conclusions These findings support the use of nivolumab for patients with recurrent/metastatic head and neck cancer regardless of prior cetuximab use or neck dissection history.

Hydroxyurea and fluorouracil (5-FU) are active cytotoxic drugs in head and neck cancer and have shown synergistic activity in vitro. Both drugs also act as radiosensitizers. Therefore, we administered radiotherapy at daily fractions of 180 to 200 cGy with simultaneous continuous infusion 5-FU at 800 mg/m2/d and escalating daily doses of hydroxyurea for five days. Cycles were repeated every other week until completion of radiotherapy. Thirty-nine inoperable patients were treated at six dose levels of hydroxyurea ranging from 500 mg to 3,000 mg orally daily. Little effect of hydroxyurea on the WBC or platelet count was noted in patients receiving less than 2,000 mg daily, whereas both parameters decreased progressively in patients receiving 2,000 mg daily or more. Mucositis occurred at all dose levels, requiring frequent dose reduction of 5-FU; however, in patients receiving a daily hydroxyurea dose of 2,000 mg or less, the median weekly 5-FU dose administered was 1,725 mg/m2 (86% of the intended 5-FU dose), whereas at daily hydroxyurea doses exceeding 2,000 mg, the median weekly 5-FU dose decreased to 1,133 mg/m2 (57%) (P = .001). Of 15 evaluable patients with recurrent disease after prior local therapy only one failed to respond; six had a complete response (CR), and eight a partial response (PR). Of 17 evaluable patients without prior local therapy, 12 had a CR, with no patient developing recurrence in the irradiated field to date; five patients had a PR. We conclude that the recommended dose of hydroxyurea in this regimen is 2,000 mg daily. That dose will cause mild to moderate myelosuppression and will allow for delivery of greater than 80% of the intended 5-FU dose. The activity of this regimen in poor-prognosis head and neck cancer exceeds 90%; its further investigation in previously untreated patients is warranted.

As part of a combined modality treatment program using chemotherapy, surgery, and/or radiotherapy, 25 patients with previously untreated stage III or IV head and neck cancer received initial combination chemotherapy. Pathologically confirmed complete remission was noted in nine patients (36%). The overall objective major response rate (with all patients included in analysis) was 68%. The chemotherapy regimen included bleomycin, cisplatin, vinblastine, methotrexate, and 5-fluorouracil. A novel concept of drug scheduling was used, based on chemotherapy-induced improvement in RBC deformability. The underlying concept is that improved RBC deformability results in improved capillary blood flow and thereby, increased drug delivery to tumor cells. Treatment resulted in moderate hematologic and renal toxicity with no treatment-related deaths. This exceptionally high, pathologically confirmed complete response rate will hopefully provide a mechanism by which combined modality therapy can adequately be tested for its ability to prolong survival of patients with advanced head and neck cancer.

Fifty-one patients with locally advanced head and neck cancer were treated with three cycles of cisplatin at 100 mg/m2 followed by 5-day continuous infusion fluorouracil (5-FU) at 1,000 mg/m2/d as induction chemotherapy. Subsequent local therapy consisted of surgery for patients with resectable disease and/or radiotherapy. Three cycles of adjuvant chemotherapy were administered to patients with partial response (PR) or complete response (CR) to induction chemotherapy. Twenty-two patients (43%) had a clinical CR that was pathologically confirmed in 12 patients (24%), and 24 patients (47%) had a PR for an overall response rate of 90%. Local therapy included surgery in 24 patients (47%) and radiotherapy alone in 22 patients (43%). Adjuvant chemotherapy was administered to 32 patients (63%) frequently at great dose reduction. At a median follow-up of 90 months, the median survival is 22 months (95% confidence interval, 15 to 36 months), and the 5-year survival is 25%, with only five patients known to be alive and disease-free at this time. The median time to progression is 14 months, with 29 patients (57%) having documented progression of their head and neck cancer and eight (16%) having progression of a second neoplasm. Seven patients died of intervening medical events. This high incidence of second malignancies supports the continued investigation of chemoprevention for patients in CR. Despite the known high response rates achieved with cisplatin and 5-FU induction chemotherapy, the overall poor survival data reported here should lead to a thorough reexamination of the frequent administration of this regimen in the community.
