Docetaxel and carboplatin chemotherapy for treating patients with stage IVB or recurrent non-squamous cell carcinoma of the uterine cervix: a phase II study.

BACKGROUND: This phase II study evaluated the efficacy and safety of docetaxel/carboplatin chemotherapy for treating patients with stage IVB or recurrent non-squamous cell carcinoma of the uterine cervix. METHODS: A total of 50 patients with International Federation of Gynecology and Obstetrics stage IVB or recurrent non-squamous cell carcinoma of the uterine cervix were enrolled and administered docetaxel at a dose of 60 mg/m2, followed by carboplatin at a dose based on the area under the receiver operating characteristic curve of 6. The treatments were repeated every 21 days until disease progression or unacceptable adverse events. Except for two patients, 48 were eligible for evaluation. Another patient withdrew consent before treatment; adverse events were evaluated in 47. RESULTS: The response rate was 47.9% with 5 patients achieving complete response, 18 partial response, 14 stable disease, and 6 progressive disease. The disease control rate was 77.1%. With a median follow-up duration of 368 days, the median progression-free survival and overall survival were 6.1 months (95% CI 5.5-8.6) and 15.8 months (95% CI 18.2-28.3), respectively. The most frequent grade 3 and grade 4 hematological toxicity was neutropenia, with 38 patients (81%) having grade 4 and 4 (9%) having grade 3 neutropenia. The non-hematological toxicities were mainly grade 1 or 2 in severity. CONCLUSION: Docetaxel/carboplatin chemotherapy was effective, with a higher disease control rate and well-tolerated chemotherapeutic regimen for patients with stage IVB or recurrent non-squamous cell carcinoma of the uterine cervix.

The Impact of Histological Subtype on Survival Outcome of Patients with Stage IIB-IVA Cervical Cancer Who Received Definitive Radiotherapy.

The impact of histologic subtype on definitive radiotherapy for patients with locally advanced cervical cancer remains unclear. The aim of this retrospective analysis was to assess clinicopathological findings and clinical outcome by histological type in patients with stage IIB-IVA cervical cancer. Ninety-two patients with stage IIB-IVA [International Federation of Gynecology and Obstetrics (FIGO) 2008] cervical cancer, who underwent definitive radiotherapy between 2013 to 2018, were identified as eligible for this study. The clinical information of the eligible patients was obtained from medical records of our hospital. Seventy-eight patients underwent concurrent chemoradiotherapy, and the remaining 14 patients received radiotherapy alone. Of 92 patients, 83 had squamous cell carcinoma (SCC) and 9 had non-SCC histology. Progression-free survival (PFS) rate of patients with non-SCC was significantly worse than of those with SCC (2-year PFS: 62.0% vs. 12.5%, p = 0.0020), but overall survival (OS) rate did not statistically differ between the two subtypes (2-year OS: 82.4% vs. 62.5%, p = 0.2157). Pelvic failure-free (PFF) rate of patients with non-SCC histology was significantly worse than of those with non-SCC (2-year PFF; 88.2% vs. 25.0%, p < 0.0001). In univariate analysis, non-SCC histology was associated with PFS rate, although there was no association with OS rate. In multivariate analysis, non-SCC histology and lymph node metastasis were independent prognostic factors for shorter PFS. In patients with stage IIB-IVA cervical cancer who underwent definitive radiotherapy, patients with non-SCC showed significantly worse PFS rate than those with SCC.

Androgen receptor in salivary gland carcinoma: A review of an old marker as a possible new target.

The role of the androgen receptor (AR) as an immunomarker for diagnosis of salivary gland duct carcinoma (SDC) is well known. Other non-squamous cell head and neck cancers (NSCC-HN), including a small subset of salivary gland cancers (SGCs), can also express AR. With the increase in effective and powerful new generation of anti-androgen agents and drugs administered orally, more targetable AR-driven NSCC-HN, such as subsets of SGCs, should be investigated for possible expression of AR. In this review, we focus on SGC subtypes, which could express AR and describe the main androgen deprivation therapy (ADT) strategies.

Multi-institutional retrospective study of mucoepidermoid carcinoma treated with carbon-ion radiotherapy.

This study aimed to evaluate the clinical outcomes of patients with mucoepidermoid carcinomas in the head and neck treated with carbon-ion radiotherapy. Data from 26 patients who underwent carbon-ion radiotherapy in four facilities were analyzed in this multi-institutional retrospective study: the Japan Carbon-ion Radiation Oncology Study Group. The median follow-up time was 34 months. One patient experienced local recurrence, and the 3-year local control rate was 95%. One patient developed lymph node recurrence and five developed distant metastases. The 3-year progression-free survival rate was 73%. Five patients died, two of mucoepidermoid carcinoma and three of intercurrent disease. The 3-year overall survival rate was 89%. Acute mucositis and dermatitis of grade 3 or higher were experienced by 19% and 8% of patients, respectively; these improved with conservative therapy. Late mucositis and osteonecrosis of jaw were observed in 12% and 23% of patients, respectively. The 3-year cumulative rate of any late adverse event of grade 3 or higher was 14%. None of the patients died of the acute or late adverse events. Carbon-ion radiotherapy was efficacious and safe for treating mucoepidermoid carcinoma in this multi-institutional retrospective study (registration no. UMIN000024473). We are currently undertaking a prospective multicenter study.

Prospective observational study of carbon-ion radiotherapy for non-squamous cell carcinoma of the head and neck.

To evaluate the efficacy and safety of carbon-ion radiotherapy for non-squamous cell carcinoma of the head and neck, 35 patients were enrolled in this prospective study. The primary end-point was the 3-year local control rate, and the secondary end-points included the 3-year overall survival rate and adverse events. Acute and late adverse events were evaluated according to the Common Terminology Criteria for Adverse Events, version 4.0. The median follow-up time for all patients was 39 months. Thirty-two and three patients received 64.0 Gy (relative biological effectiveness) and 57.6 Gy (relative biological effectiveness) in 16 fractions, respectively. Adenoid cystic carcinoma was dominant (60%). Four patients had local recurrence and five patients died. The 3-year local control and overall survival rates were 93% and 88%, respectively. Acute grade 2-3 radiation mucositis (65%) and dermatitis (31%) was common, which improved immediately with conservative therapy. Late mucositis of grade 2, grade 3, and grade 4 were observed in 11, one, and no patients, respectively. There were no adverse events of grade 5. Carbon-ion radiotherapy achieved excellent local control and overall survival rates for non-squamous cell carcinoma. However, the late mucosal adverse events were not rare, and meticulous treatment planning is required. Trial registration no. UMIN000007886.

Neoadjuvant chemotherapy with docetaxel and carboplatin followed by radical hysterectomy for stage IB2, IIA2, and IIB patients with non-squamous cell carcinoma of the uterine cervix.

BACKGROUND: We conducted a phase II study to evaluate the efficacy of neoadjuvant chemotherapy with docetaxel and carboplatin followed by radical hysterectomy for patients with non-squamous cell carcinoma of the uterine cervix. METHODS: Sixty-one patients with International Federation of Gynecology and Obstetrics stage IB2, IIA2, or IIB non-squamous cell carcinoma of the uterine cervix were enrolled. The patients were administered docetaxel at a dose of 60 mg/m2, followed by carboplatin at a dose based on an area under the curve of 6. The treatments were repeated every 21 days for one to three cycles. Fifty-two patients were eligible to evaluate the efficacy of neoadjuvant chemotherapy followed by radical hysterectomy. Adverse events were evaluated in 59 patients. RESULTS: The response rate was 69 % (95 % CI, 57-82 %), with 5 patients achieving complete response, 31 partial response, 15 stable disease, and 1 progressive disease. Median follow-up duration was 1913 days with a range of 145-2632 days. Of 52 patients, 50 underwent radical hysterectomy after neoadjuvant chemotherapy. The 2-year overall survival rate was 81.8 % for stage IB2, 85.7 % for stage IIA2, and 92.6 % for stage IIB. The most frequent grade 3 and 4 hematological toxicity was neutropenia, with 43 patients experiencing grade 4 and 11 with grade 3. The nonhematological toxicities were mainly grade 1 or 2 in severity. CONCLUSION: Neoadjuvant chemotherapy with docetaxel and carboplatin followed by radical hysterectomy may be a useful strategy for patients with non-squamous cell carcinoma of uterine cervix.

Understanding immunotherapy for the treatment of non-small cell lung cancer.

Patients diagnosed with advanced non-small-cell lung cancer (NSCLC) (either squamous or non-squamous) have previously had limited treatment options after progression on chemotherapy. With the emergence of new drugs, particularly in the immuno-oncology setting, this is now changing. Recent clinical trial evidence demonstrates that compared with docetaxel, patients who received nivolumab had better overall survival and also significantly fewer grade 3-4 adverse events. This article reviews the clinical trial data for nivolumab and provides an overview of how this drug works. The adverse event profile of nivolumab is assessed and compared to that of docetaxel. The important role that nurses can play in supporting patients on nivolumab is also discussed.

Advanced non-squamous NSCLC with no actionable oncogenic driver in Spain: a cross-sectional descriptive analysis of data from the Thoracic Tumor Registry.

BACKGROUND: Non-small cell lung cancer (NSCLC) accounts for the vast majority of all diagnosed lung cancers. According to their histology, most NSCLCs are considered non-squamous cell carcinoma (NSCC), and up to 85% of the latter may lack either one of the two main actionable oncogenic drivers (i.e., EGFR mutations and ALK rearrangements). OBJECTIVE: Our analysis aimed to describe the clinical and epidemiological characteristics of Spanish patients suffering from NSCC with no actionable oncogenic driver in daily clinical practice. DESIGN: A retrospective, cross-sectional, descriptive analysis. METHODS: We analyzed the records of all Spanish patients with advanced NSCC diagnosed between January 2011 and January 2020 and included in the Spanish Thoracic Tumor Registry database. We evaluated the presence of metastasis and molecular profiling at the time of diagnosis and treatments received. We also assessed overall survival (OS) and progression-free survival (PFS) according to first-line treatment. RESULTS: One thousand seven hundred ninety-seven Spanish patients with NSCC were included. They were mainly men (73.2%), smokers (current [44.4%] and former [44.4%]) and presented adenocarcinoma histology (97.6%). Most patients had at least one comorbidity (80.4%) and one metastatic site (96.8%), and a non-negligible number of those tested were PD-L1 positive (35.2%). Notably, the presence of liver metastasis indicated a shorter median OS and PFS than metastasis in other locations (p < 0.001). Chemotherapy was more often prescribed than immunotherapy as first-, second-, and third-line treatment in that period. In first-line, the OS rates were similar in patients receiving either regimen, but PFS rates significantly better in patients treated with immunotherapy (p = 0.026). Also, a high number of patients did not reach second- and third-line treatment, suggesting the failure of current early diagnostic measures and therapies. CONCLUSIONS: This analysis of the most lethal tumor in Spain could highlight the strengths and the weaknesses of its clinical management and set the ground for further advances and research.

Inflammatory Myofibroblastic Tumor After Receiving Treatment for Non-small Cell Carcinoma.

Inflammatory pseudotumor encompasses a spectrum of both neoplastic and non-neoplastic conditions characterized by a histological pattern featuring a proliferation of cytologically bland spindle cells, accompanied by a prominent chronic inflammatory infiltrate. Within this spectrum, inflammatory myofibroblastic tumor (IMT) has emerged as a distinct entity over the past two decades, marked by unique clinical, pathological, and molecular characteristics. Typically affecting the visceral soft tissues of children and adolescents, IMT exhibits a propensity for local recurrence while posing a minimal risk of distant metastasis. They are extremely rare in adults, constituting less than 1% of adult lung tumors. Our patient, a 63-year-old female, has an intricate medical background, encompassing chronic obstructive pulmonary disease (COPD), a previous history of smoking (35 pack-years, quit a year before admission), coronary artery disease, non-obstructive hypertrophic cardiomyopathy, and obstructive sleep apnea. Presenting with a diagnostic dilemma, she recently received treatment for non-small cell carcinoma with radiation therapy, which has evolved into a swiftly advancing case of IMT.

A Random Forest Model for Post-Treatment Survival Prediction in Patients with Non-Squamous Cell Carcinoma of the Head and Neck.

BACKGROUND: Compared to squamous cell carcinoma, head and neck non-squamous cell carcinoma (HNnSCC) is rarer. Integrated survival prediction tools are lacking. METHODS: 4458 patients of HNnSCC were collected from the SEER database. The endpoints were overall survivals (OSs) and disease-specific survivals (DSSs) of 3 and 5 years. Cases were stratified-randomly divided into the train & validation (70%) and test cohorts (30%). Tenfold cross validation was used in establishment of the model. The performance was evaluated with the test cohort by the receiver operating characteristic, calibration, and decision curves. RESULTS: The prognostic factors found with multivariate analyses were used to establish the prediction model. The area under the curve (AUC) is 0.866 (95%CI: 0.844-0.888) for 3-year OS, 0.862 (95%CI: 0.842-0.882) for 5-year OS, 0.902 (95%CI: 0.888-0.916) for 3-year DSS, and 0.903 (95%CI: 0.881-0.925) for 5-year DSS. The net benefit of this model is greater than that of the traditional prediction methods. Among predictors, pathology, involved cervical nodes level, and tumor size are found contributing the most variance to the prediction. The model was then deployed online for easy use. CONCLUSIONS: The present study incorporated the clinical, pathological, and therapeutic features comprehensively and established a clinically effective survival prediction model for post-treatment HNnSCC patients.

Carboplatin and weekly paclitaxel in combination with bevacizumab for the treatment of advanced non-small cell lung cancer complicated by idiopathic interstitial pneumonias: A feasibility study.

BACKGROUND: Idiopathic interstitial pneumonias are an independent risk factor of lung cancer, and a chemotherapy-induced acute exacerbation is the most common lethal complication in Japanese patients. The safety and efficacy of carboplatin and weekly paclitaxel for the treatment of non-small cell lung cancer with idiopathic interstitial pneumonias has been previously reported in prospective studies. However, carboplatin + paclitaxel with bevacizumab is currently the standard therapy. We conducted a multicenter, phase II study to confirm the safety and efficacy of carboplatin + weekly paclitaxel + bevacizumab for the treatment of patients with lung cancer complicated by idiopathic interstitial pneumonias. METHODS: Chemotherapy-naïve patients with advanced-stage or patients with post-operative recurrent non-squamous non-small cell lung cancer complicated by idiopathic interstitial pneumonias were enrolled. Patients received carboplatin (area under the curve: 5.0) and bevacizumab (15 mg/kg) on day 1 and paclitaxel (100 mg/m2) on days 1, 8, and 15 of each 4-week cycle. RESULTS: Seventeen patients less than the predetermined number were enrolled and received a median of four treatment cycles (range: 1-6). One patient (5.9%; 95% confidence interval: 0.1-28.7%) had acute exacerbation of interstitial pneumonia related to the study treatment which improved after corticosteroid treatment. The overall response rate was 52.9%. The median progression-free survival, median survival time, and 1-year survival were 5.7 months, 12.9 months, and 52.9%, respectively. CONCLUSION: The addition of bevacizumab to carboplatin and weekly paclitaxel might be safe and effective for the treatment of advanced non-small cell lung cancer complicated by idiopathic interstitial pneumonias.

Next-generation sequencing clarified why first-line treatment with osimertinib was ineffective in an autopsied case of EGFR-mutated lung squamous cell carcinoma.

Epidermal growth factor receptor (EGFR)-mutated squamous cell carcinoma (SCC) is less common than adenocarcinoma. The third-generation EGFR-tyrosine kinase inhibitor, osimertinib, is effective in EGFR-mutated lung adenocarcinoma, but its efficacy in EGFR-mutated lung SCC is unclear. The patient was an 83-year-old male. He was diagnosed with SCC of the lung, and molecular analysis revealed that the tumor was positive for EGFR exon19 deletion. He was treated with osimertinib 80 mg/day. No adverse events were observed, but after 18 days of therapy, he complained of dyspnea, and a computed tomography scan showed enlarged lung cancer. The case was categorized as a progressive disease. The patient died 3 weeks later. The autopsy findings confirmed the diagnosis of lung SCC, with morphology and immunohistochemical staining identical to the tumor obtained by bronchoscopy. Next-generation sequencing showed the presence of TP53 R158L, CDK6, and KRAS amplifications. The current case report shows that next-generation sequencing can explain why osimertinib is ineffective in EGFR-mutated SCC.

Survival Outcomes of Non-squamous Cell Carcinoma and Rare Squamous Cell Carcinoma Variants of the Larynx.

The literature focuses primarily on laryngeal differentiated squamous cell carcinoma (SCC), and only a limited number of studies have evaluated the outcomes of rare variants of SCC (vSCC) and non-SCC malignancies (nSCC). To our knowledge, this is the first study to compare the survival outcomes of these two groups. We retrospectively reviewed the records of 816 patients who underwent laryngeal surgery from January 2010 to November 2022. Forty-nine (6.2%) were identified as having unusual larynx malignancies and categorized in the nSCC or vSCC groups. The patients' clinicopathological features were then recorded. We compared the two groups' overall survival (OS) and recurrence-free survival (RFS) outcomes. Thirty-three (4.2%) patients had vSCC, and 16 (2%) had nSCC. Forty-two (85.7%) were male, and the mean age was 58.57 years. The median follow-up time was 69 months. The 5-year OS rate was 71.4% in the nSCC group vs. 87.9% in the vSCC group (p = .055). Only surgical margin (HR: 4.68; 95% CI:1.13-19.37, p = .033) was an independent prognostic factor for OS in the multivariable analysis. The 5-year RFS rate was 50% for the nSCC group compared to 90.9% for the vSCC group (p < .001). In the multivariable analysis, surgical margin positivity (HR: 21.0, 95% CI 3.97-98.1, p < .001), and lymphovascular invasion (HR: 0.043, 95% CI 0.005-0.357, p = .004) were independent prognostic factors for RFS. Although OS did not show a statistical difference, nSCC malignancies of the larynx demonstrated worse OS and RFS outcomes than vSCC malignancies.

A Phase II Study of S-1 plus Oxaliplatin for Patients with Recurrent Non-Squamous Cell Carcinoma of the Uterine Cervix (Tohoku Gynecologic Cancer Unit: TGCU206 Study).

Recurrent non-squamous cell carcinoma (non-SCC) of the uterine cervix is resistant to treatment and has a poor prognosis. The efficacy and safety of S-1/oxaliplatin (SOX) therapy in patients with recurrent non-SCC was examined in a phase II study. Fifteen patients were enrolled between August 2013 and March 2023. S-1 was administered orally at a daily dose of 80-120 mg for 14 days, and oxaliplatin was administered intravenously at a dose of 100 mg/m2 on day 1. Each treatment cycle lasted 21 days. The anti-tumor effects, adverse events, progression-free survival (PFS), and overall survival (OS) were investigated. The median patient age was 54 (41-74) years. The anti-tumor effect was rated as a partial response in five patients, stable disease in four, and progressive disease in 6. The overall response rate was 33% and the disease control rate was 60%. Regarding hematologic toxicities of grade 3 or more severity, leukopenia, neutropenia, anemia, and thrombocytopenia occurred in 26.6-40.0%. None of the patients discontinued the treatment because of adverse events. The median PFS and OS were 6 months (95% confidence interval [CI]: 2-11 months) and 22 months (95% CI: 11-23 months), respectively. No treatment-related deaths occurred. These results suggest that SOX therapy is useful for the treatment of recurrent non-SCC with promising anti-tumor effects and minimal adverse events.

Unusual Presentation of Primary Pulmonary Sarcomatous Cancer With Brain Metastasis: A Case Report.

Pulmonary sarcomatous carcinoma is a rare subtype of non-small cell lung cancer (NSCLC). This cancer has very low survival rates primarily due to its aggressive nature and propensity for early spread to abdominal organs and the skeletal system. Remarkably, brain metastasis is observed at later stages of the disease, likely attributing to the high fatality rate after the disease progresses to the brain tissue. In our case, a 79-year-old female with a 45-pack-year smoking history sought medical attention at a primary care clinic due to a 3-month history of recurrent right-sided chest pain. Notably, she denied cough, sputum production, palpitations, or syncope. CT chest revealed a 6.8 x 3.5 cm mass in the right upper lobe (RUL) of the lung, with evidence of obstruction and infiltration of the adjacent chest wall. A PET scan indicated increased uptake in the mass and the presence of smaller pulmonary nodules in both lungs, and multiple nodules in the upper left arm, abdomen, right inguinal region, left thigh, and cecum. Importantly, no intracranial lesions were detected. A subsequent colonoscopy yielded normal findings. Histopathologic examination of the lung mass and cell markers was consistent with a diagnosis of sarcomatous carcinoma of the lung. Only three days after the initial clinic visit, the patient presented with numbness and tingling in her lower extremities. Brain MRI revealed multiple bilateral brain metastases accompanied by significant vasogenic edema, prompting treatment with steroid therapy and brain radiation therapy. Subsequent chemotherapy/immunotherapy with Nab-paclitaxel /carboplatin/atezolizumab was initiated but led to significant treatment-related toxicities. Consequently, the treatment plan was adjusted to a single dose of single-agent immunotherapy using pembrolizumab. Unfortunately, the patient chose to discontinue treatment and eventually passed away after 13 days of palliative care. Compared to other lung cancer subtypes, brain metastasis in sarcomatous lung cancer is infrequent due to its lower prevalence among all lung cancer cases. Furthermore, sarcomatous lung cancer has a reduced propensity for developing brain metastasis when compared to other forms of non-small cell lung cancer (NSCLC). Regrettably, the prognosis for sarcomatous lung cancer with brain metastasis remains generally unfavorable, signaling an advanced stage of the disease with limited treatment options.

Non-Squamous Cell Malignancies of the Larynx.

OBJECTIVES/HYPOTHESIS: Non-squamous cell carcinoma (SCC) malignancies are rare, but well described laryngeal pathologies. However, the epidemiology and clinical behavior of these tumors is not well studied. STUDY DESIGN: Retrospective cohort study. METHODS: Patients diagnosed with non-squamous cell larynx cancer from 2004 to 2017 in the National Cancer Database were selected. Demographic, clinicopathologic factors, treatments, and survival were analyzed. Univariable and multivariable cox regression were performed. Survival was compared with a propensity score-matched (PSM) population of laryngeal SCC patients. RESULTS: A total of 136,235 cases of larynx cancer were identified. After excluding SCC variants, 2,172 (1.6%) patients met inclusion criteria. The most common histology was chondrosarcoma (374, 17.2%), followed by small cell (345, 15.9%), and spindle cell carcinoma (268, 12.3%). The most common treatment was surgery (683, 31.4%) followed by chemoradiation (409, 18.8%) and surgery and adjuvant radiation (288, 13.3%). Overall, 3- and 5-year survival was 67.9% and 59.4%, respectively. In multivariate analysis controlling for age, stage, comorbidity, histology, and treatment modality; chondrosarcoma had the best survival (hazard ratio [HR] 0.11, confidence interval [CI] 0.07-0.19, P < .001). In a PSM population, matched for age, stage, comorbidity, and treatments; non-SCC patients had significantly lower survival (51.5% vs. 59.9%, P < .001). CONCLUSION: A diverse range of non-squamous cell malignancies occur in the larynx. In general, these tumors have poor survival, with few exceptions such as chondrosarcoma. While the majority of these histologies undergo surgical-based treatments in other sites, only 53% of patients underwent surgical-based treatment in the larynx. These data could guide clinicians in determining the outcome of treatment in these patients. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1771-1777, 2022.

Nivolumab for recurrent or metastatic head and neck cancer patients with non-squamous cell carcinoma and/or a primary subsite excluded from CheckMate141, a retrospective study.

OBJECTIVES: In CheckMate 141, nivolumab significantly improved overall survival (OS) in patients with platinum-refractory recurrent or metastatic squamous cell carcinomas (R/M SCC) of the head and neck. However, reports on nivolumab for patients with non-SCC and/or a primary subsite excluded from CheckMate 141 are limited. MATERIALS AND METHODS: We conducted a retrospective analysis of R/M head and neck cancer patients who received nivolumab. The study subject excluded patients with squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, and larynx. RESULTS: A total of 59 patients were included, consisting of 40 males and 19 females with a median age of 61 years. Half of the patients had non-SCC histology. The main primary site included the sinonasal cavity (n = 18), salivary gland (n = 15), and nasopharynx (n = 13). Three (6.0%) patients achieved a complete response and 5 (10.0%) a partial response, giving an overall response rate (ORR) of 16.6%. Median time-to-treatment failure (TTF) and OS were 3.7 and 16.2 months, respectively. Salivary gland and nasopharyngeal cancer achieved relatively higher ORR (25.0 and 36.4%, respectively). On analysis by primary site, nasopharyngeal cancer showed a significantly better TTF and OS than the other primary sites. On analysis by histological findings, no significant difference in TTF and OS was observed between non-SCC and SCC. CONCLUSION: Nivolumab for cancers involving the salivary gland/nasopharynx and non-SCC histology showed comparable efficacy to that in CheckMate 141. This result indicates that nivolumab may be effective even for patients not included in CheckMate 141.

Multicenter Study of Carbon-ion Radiotherapy for Oropharyngeal Non-squamous Cell Carcinoma.

BACKGROUND/AIM: To evaluate treatment outcomes of carbon-ion radiotherapy for oropharyngeal non-squamous cell carcinoma at four carbon-ion facilities in Japan. PATIENTS AND METHODS: We retrospectively analyzed the cases of 33 patients with oropharyngeal non-squamous cell carcinoma who were treated with carbon-ion radiotherapy between November 2003 and December 2014. RESULTS: The histology included adenoid cystic carcinoma (n=25) and mucosal malignant melanoma (n=4). No patients had T1 tumors; 23 had T4 tumors. The most-commonly prescribed dose was 57.6 Gy (RBE) in 16 fractions. The median follow-up period was 34.8 months (range=4.2-122.8 months). The 3-year local control and overall survival rates were 94.7% and 90.7%, respectively. There were no grade ≥4 acute adverse events. Only one patient experienced a grade ≥4 late adverse event. No patients experienced late adverse events related to swallowing or salivary function. CONCLUSION: Carbon-ion radiotherapy appears to be a promising treatment option for oropharyngeal non-squamous cell carcinoma.

Treatment and outcomes for early non-small-cell lung cancer: a retrospective analysis of a Portuguese hospital database.

AIM: This observational study evaluated treatment patterns and survival for patients with stage I-IIIA non-small-cell lung cancer (NSCLC). MATERIALS & METHODS: Adults newly diagnosed with NSCLC in 2012-2016 at IPO-Porto hospital were included. Treatment data were available for patients diagnosed in 2015-2016. RESULTS: 495 patients were included (median age: 67 years). The most common treatments were surgery alone or with another therapy (stage I: 66%) and systemic anticancer therapy plus radiotherapy (stage II: 54%; stage IIIA: 59%). One-year OS (95% CI) for patients with stage I, II and IIIA NSCLC (diagnosed 2012-2016) were 92% (88-96), 71% (62-82) and 69% (63-75), respectively; one-year OS (95% CI) for treated patients with stage I-II or stage IIIA NSCLC (diagnosed 2015-2016) were 89% (81-97) and 86% (75-98) for non-squamous cell and 76% (60-95) and 49% (34-70) for squamous cell NSCLC. CONCLUSION: Treatment advances are strongly needed for stage I-IIIA NSCLC, especially for patients with squamous cell histology.

Docetaxel plus cisplatin in recurrent and/or metastatic non-squamous-cell head and neck cancer: a multicenter phase II trial.

The clinical utility of systemic therapy and genomic profiling in non-squamous-cell head and neck cancer (NSCHNC) has not been fully elucidated. This phase II trial evaluated the efficacy and safety of docetaxel and cisplatin combination in the first-line setting. Eligibility criteria were recurrent and/or metastatic NSCHNC; progressive disease within the last 6 months; no prior systemic therapy; and ECOG performance status of 0-1. Patients received docetaxel (75 mg/m2 on day 1) and cisplatin (75 mg/m2 on day 1), repeated every 21 days for 6 cycles. The primary endpoint was confirmed objective response rate (ORR). The secondary endpoints included progression-free survival (PFS), overall survival (OS), and adverse events. Next-generation sequencing (NGS) was performed using the Ion AmpliSeq Cancer Hotspot Panel v2. Twenty-three patients were enrolled from November 2012 to October 2016, of whom 8 were male. Median age was 57 years. Ninety-six percent of cases were metastatic. Among 22 evaluable patients, confirmed ORR was 45% (95% confidential interval 24-68%). With a median follow-up period of 18.8 months, median PFS and OS were 6.7 and 20.1 months, respectively. Grade 3/4 adverse events included febrile neutropenia (39%) and anemia (22%). No treatment-related deaths were observed. NGS analysis revealed potential treatment targets, including ERBB2, KIT, and ALK. The docetaxel and cisplatin combination regimen can be considered a new treatment option in recurrent and/or metastatic NSCHNC, although primary prophylaxis for febrile neutropenia should be considered. Diverse genomic alterations may lead novel treatment options.This trial was registered with the UMIN Clinical Trials Registry as UMIN000008333 on [September 1st, 2012].
