RESUMO

Tracheal squamous cell carcinoma is the most common pathology in smokers while ACC is more prevalent among non-smokers. These tumors tend also to be diagnosed late on account of delayed specific symptoms as hemoptysis, dyspnea, cough, hoarseness, and stridor being the most common. Management of tracheal tumors is essentially multidisciplinary. It includes interventional endoscopy, surgery, radiotherapy, and/or end luminal brachytherapy. Extensive segmental resection of the trachea is the potentially curative treatment of choice for primary lesion. The sleeve trachea resection is one of the optimal surgical modalities. The other options are: partial tracheal wall resection and immediate tracheal reconstruction, total laryngectomy plus partial resection of trachea and primary reconstruction, laryngeo-tracheal resection, cervico-mediastinal exenteration, or carinal resection and reconstruction. Trachea anastomosis is suitable for small defects. The platysma myocutaneous flap combined with the facial flap of the sternohyoid muscle, sternocleidomastoid myoperiosteal flap and the pectoralis major musculocutaneous flap are applied to reconstruct the defects of cervical trachea. Post-operative radiation therapy, in many cases, is considered a fundamental part of treatment. Contraindications to surgery include: metastatic disease, invasion of adjacent organs, involvement of airway greater than could be safely resected (i.e. >50% of trachea), involvement of airway that would leave grossly positive margins after resection, spinal kyphosis, or poor medical condition of the patient. Patients in the current report tolerated therapy well with the use of modern RT techniques and dose delivery to 60 to 64 Gy to a large extent of the central airway. Additional data and meta-analysis are required to validate the efficacy of chemoradiation in comparison to primary RT alone for unresectable cases and subsequently identify improved systemic therapies. Further investigation into the potential role of additional therapies, such as adjuvant chemotherapy or immunotherapy, may be worth exploring. Our initial findings suggest the use of concurrent chemotherapy in addition to RT in patients with locally advanced tracheal SCC.

RESUMO

INTRODUCTION: Globally, there is marked variation in overall incidence and presentation of head and neck cancers, these cancers account for 11.5 per 100,000 population in G.C.C states. Concomitant chemotherapy and external beam radiotherapy (EBRT) is indicated in such cancers with aim of organ preservation, control and possible cure. Hyper fractionated radiotherapy with concomitant chemotherapy or cetuximab is a lesser explored option. In this study we wish to assess the tolerability and efficacy of cetuximab with altered fractionation and compare this with the chemotherapy (cisplatin). MATERIALS AND METHODS: This is a randomized controlled study from a single institute in Kuwait. Locally advanced head and neck cancer cases excluding cancer nasopharynx are enrolled for the study. Stage III or stage IV-A cases were enrolled with histopathology squamous cell carcinoma. Patients were randomized into 2 arms. Arm A: to receive platinum-based CT i.e. cisplatin in a dose of 100 mg/m2 3-weekly or 40 mg/m2 weekly during radiation; Arm B: received cetuximab with a loading dose 400 mg/m², one week before radiation followed by weekly dose of 250 mg/m² during radiation. Radiotherapy was delivered using intensity modulated radiotherapy (IMRT) or 3D-conformal radiotherapy (CRT). The primary objective was to evaluate whether the use of cetuximab with concurrent hyperfractionated radiation regimen will have loco regional control rates (LC) and Disease-free survival (DFS) that are comparable to concurrent cisplatin in patients with LAHNC. The secondary endpoints were to compare the impact of using concurrent cetuximab vs chemotherapy regimen on Overall Survival of patients (OS) and acute and late adverse events. RESULTS: From November 2012 to November 2017, 40 patients were randomized. The median age of was 51 years (range 27-72 years). Thirty-five patients are male and remaining was female. 14 patients have their primaries in larynx, 11 in oropharynx, 8 in oral cavity, and 5 has tumor in hypopharynx. Two patients had disease in nasal sinus or overlapping subsides. 50% has T4 lesions while 35% has T3 lesions, Nodal status was (N0-1) in 20 patients and (N2-3) in 20 patients. Overall staging showed a majority to have stage IV disease (63%). HPV was negative in 2 cases in Arm 1 and positive in 2 cases in Arm 2. 22 patients were randomly allocated in Arm A (platinum-based) while 18 were in Arm B (cetuximab). CR was achieved in 59% in arm A vs 50% in Arm B, while PR was 27.3% and 27.8% respectively. Disease progressed in 2 patients in Arm B only. Out of these 40 patients, 14 patients failed (6 and 8 in arm A and B respectively). Locoregional failure was documented in 6 (27.3%) vs 7 (38.9%) of arm A and B respectively, which was statistically not significant possibly related with lower number of cases. 2 years DFS was 56.5% vs 77.3% in cisplatin vs cetuximab arm (denoting nonsignificant increase of relapse rate in cisplatin arm). However, 2 years OS was 80.7% vs 57.3% in cisplatin and cetuximab arm respectively (p value=0.04). CONCLUSION: Though cetuximab has lesser side effects but it is not indicated in treatment of LAHNC. Concurrent cisplatin is a trusted option for concomitant setting regardless of the HPV status and tumor location. However, in the context of cisplatin ineligible patients, cetuximab should be used only with hyper fractionation. This preliminary study could represent a good core of large international multicenter RCT.

RESUMO

BACKGROUND: Compared to other regions of the world, palliative care (PC) in the Eastern Mediterranean region is at an earlier stage of development. The Palliative Care Center of Kuwait (PCC-K) was established a few years ago as the first stand-alone PC center in the region. This study was conducted to investigate the timing of referral to the PCC-K and its outcome. METHODS: Retrospective review of referrals to the PCC-K during its first 3 years of action. Late referral was defined as referral during the last 30 days of life. RESULTS: During the 3-year period, 498 patients with cancer were referred to the PCC-K of whom 467 were eligible for analysis. Referral was considered late in 58% of patients. Nononcology facilities were more likely to refer patients late when compared to oncology facilities ( P = .033). The palliative performance scale (PPS) was ≤30 in 59% of late referrals and 21% in earlier referrals ( P < .001). Among 467 referred patients, 342 (73%) were eligible for transfer to the PCC-K, 102 (22%) were ineligible, and 23 (5%) died before assessment by the PCC-K consultation team. From the 342 eligible patients, the family caregivers refused the transfer of 64 (19%) patients to the PCC-K. CONCLUSION: Patients are frequently referred late to the PCC-K. Further research to identify barriers to PC and its early integration in Kuwait is required. The PPS may be useful in identifying late referrals.
