Poor Treatment

Hypopharyngeal carcinoma is relatively rare and has the worst prognosis of all head and neck cancers. Initially, surgery followed by postoperative radiation was the standard of care for locally advanced disease. In the recent years, various organ sparing approaches have evolved. There are mainly two schools of thought regarding larynx preservation in hypopharyngeal cancers which include either induction chemotherapy followed by response assessment for radical radiotherapy or concurrent chemoradiation. An ongoing trial is comparing the effectiveness between these two established approaches. The role of anti-EGFR therapy and immunotherapy is still being evaluated. Despite all the advancements in treatment, hypopharyngeal cancers are still associated with poor treatment outcomes.

Radiotherapy Alone

Nasopharyngeal carcinoma is highly radio- and chemosensitive tumor with its unique clinical and biological behavior. Treatment of stage I disease is radical radiotherapy alone. For stage II disease treatment is radiotherapy with or without chemotherapy. The standard of care for locally advanced nasopharyngeal cancer (stages III-IVB) is concurrent chemoradiation. Optimum timing and sequence of chemotherapy are not yet well-defined. The role of adjuvant and induction chemotherapy is debatable. Here we are going to highlight the role of chemotherapy in nasopharyngeal carcinoma, its benefit, and controversies regarding timing and sequences.

Larynx Preservation

In this article, we aimed to discuss the role of total laryngectomy (TL) in the management of patients with larynx cancer (LC) in the era of organ preservation. Before the 1990s, TL followed by radiotherapy (RT) was the standard treatment for patients with locally advanced LC. Over the last 30 years, various types of larynx preservation (LP) programs associating induction or concurrent chemotherapy (CT) with RT have been developed, with the aim of treating locally advanced LC patients while preserving the larynx and its functions. Overall, more than two-thirds of patients included in a LP program will not require total laryngectomy (TL) and will preserve a functional larynx. However, despite these advances, the larynx is the only tumor site in the upper aero-digestive tract for which prognosis has not improved during recent decades. Indeed, none of these LP protocols have shown any survival advantage compared to primary radical surgery, and it appears that certain LC patients do not benefit from an LP program. This is the case for patients with T4a LC (extra-laryngeal tumor extension through the thyroid cartilage) or with poor pretreatment laryngeal function and for whom primary TL is still the preferred therapeutic option. Moreover, TL is the standard salvage therapy for patients with recurrent tumor after an LP protocol.

Distant Failure

Induction chemotherapy (IC) in locally advanced head and neck squamous cell carcinoma (LA HNSCC) has been used for decades. However, its role is yet to be clearly defined outside of larynx preservation. Patients with high risk of distant failure might potentially benefit from sequential treatment. It is now widely accepted that TPF (docetaxel, cisplatin, and fluorouracil) is the standard IC regimen. Essays that have compared this approach with the standard of care, concurrent chemoradiotherapy (CCRT), are mostly inconclusive. Radiotherapy (RT) can be used in the post-IC setting and be sensitized by chemotherapy or cetuximab. Again, no consensus exists but there seems to be trend in favor of potentiation by cisplatin. Less toxic schemes of IC are tested as toxicity is a major issue with TPF. IC might have an interesting role in human papilloma virus (HPV)-related LA HNSCC and lead to CCRT de-escalation.

Molecular Alterations

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal soft tissue sarcoma of the gastrointestinal tract. The management of locally advanced or metastatic unresectable GIST involves detecting KIT, PDGFR, or other molecular alterations targeted by imatinib and other tyrosine kinase inhibitors. The role of immunotherapy in soft tissue sarcomas is growing fast due to multiple clinical and pre-clinical studies with no current standard of care. The potential therapies include cytokine-based therapy, immune checkpoint inhibitors, anti-KIT monoclonal antibodies, bi-specific monoclonal antibodies, and cell-based therapies. Here we provide a comprehensive review of the immunotherapeutic strategies for GIST.

Total Neoadjuvant Therapy

3509 Background: Clinical response following neoadjuvant therapy is paramount to identifying locally advanced rectal cancer (LARC) patients suitable for Watch and Wait (WW). A 3-tier schema was devised to stratify clinical response. Patients with a complete clinical response (cCR) are considered for WW, while those with an incomplete clinical response (iCR) are recommended for total mesorectal excision (TME). A near complete response (nCR) tier captures patients with significant, but not complete, response to be considered for WW. This schema’s efficacy has yet to be validated. We investigated survival and organ preservation (OP) rates based on this 3-tier clinical response assessment in patients with LARC who underwent total neoadjuvant therapy (TNT) in a prospective, multi-center clinical trial. Methods: Patients with MRI stage II and III rectal adenocarcinoma were randomized to either induction chemotherapy (FOLFOX or CAPEOX) followed by chemoradiation or chemoradiation followed by consolidation chemotherapy (FOLFOX or CAPEOX). At 8+/-4 weeks following TNT, response on digital rectal and endoscopic examinations was evaluated by the 3-tier schema. The date of this restaging clinical response assessment was used as time zero. The endpoints of rate of OP, disease-free survival (DFS), TME-free DFS, and overall survival (OS) were evaluated using the Kaplan-Meier method with differences analyzed by the log-rank test. Results: Clinical response assessments were available for 294 patients. The median time to assessment after neoadjuvant therapy was 7.9 weeks. Based on the 3-tier schema, 124 patients were categorized as cCR, 113 as nCR, and 57 as iCR. Baseline age, sex, average distance from the anal verge, clinical T classification, and clinical N classification were similar between the response groups. The table shows the 3-year rates of OP, DFS, TME-free DFS, and OS. The median follow-up was 2.36 years. Of the patients with a nCR, the 3-year TME rate was 48% compared with 21% in the cCR group. Conclusions: The 3-tier clinical response assessment has prognostic implications for OP and DFS in patients with LARC who underwent TNT. In patients with a nCR, more than half achieved OP at 3 years. This information should be utilized to counsel patients regarding their expected outcomes. Clinical trial information: NCT02008656. [Table: see text]

15541 Management of Stage III or IV Head and Neck (H&N) cancer is debatable. Standard of care is Radical Surgery (Sx) followed by Radiotherapy (XRT). However, cosmetic and functional complications are distressing and result in decreased quality of life. Therefore, organ preservation has become important when deciding best management. The VA larynx study, the EORTC 24891 and the 91–11 US intergroup trial have shown efficacy of organ preserving chemoradiotherapy (Cx+Rx) comparable to Sx and XRT. These studies are limited to laryngeal and hypopharyngeal cancers and whether same principles can be applied to other H&N sites is unknown. We conducted a retrospective study of stage III & IV H&N cancer treated at our Institution between 1996–2004 to evaluate survival, organ preservation and toxicities. 45 males between 47 to 83 years (median 59.6) were studied. 87% were white and 13% black. 82% had history of tobacco and alcohol abuse, 4% tobacco only, 11% alcohol only and 2% never smoked or drank. The sites of disease were: nasopharynx 1 (2%), oropharynx 19 (42%), base of tongue 10 (22%), larynx 6 (13%) and pharynx 9 (20%). 15 patients (33%) where stage III and 30 (67%) stage IV. The treatment was combined Cx+Rx. The mean dose of XRT was 6697 Cgy and mean cycles of chemotherapy (Cx) were 2.2. Of those, 42 patients (93%) received cisplatin and 5FU, 2 (4%) carboplatin and 5FU and 1 (2%) carbo only. 10 patients (22%) received additional Cx and 14 (31%) underwent additional Sx (neck dissection). 19 patients (42%) are alive, 19 (42%) are death and 7 (16%) were lost to f/u. Median survival is 30.6 months. 1 patient was refractory and 6 relapsed in less than a year. Among them, 4 were local relapses, 1 a neck recurrence (no prior dissection) and 1 a distant relapse. The most common acute toxicities were: Anemia 87%, neutropenia 64%, hyperglycemia 82%, transient elevation of BUN 60% and creatinine 36%, hypo/hypernatremia 64%, severe mucositis 71%, weight loss 76%, N/V 47% and severe dysphagia 27%. Cx+Rx appears to be a safe, feasible and comparable alternative to Sx regardless of the anatomical origin in locally advanced H&N cancer, with the advantage of organ preservation. Additional XRT boost, Cx or Sx could decrease relapses. Further studies are warranted to validate these hypotheses. No significant financial relationships to disclose.

High Incidence

Cervical cancer is the second most common cause of female cancer mortality worldwide. Concurrent chemoradiotherapy represents the standard of care for patients with stage IB2-IIIB cervical cancer. However, the lack of radiotherapy departments, especially in developing countries, the presumed high incidence of long-term complications, and the poor control of metastatic disease have brought about the development of different therapeutic approaches such as neoadjuvant chemotherapy followed by surgery. We reviewed the literature concerning the role of neoadjuvant chemotherapy for locally advanced cervical cancer.
