Androgen deprivation in combination with novel hormonal agents, docetaxel, or in combination with abiraterone/prednisone plus docetaxel or darolutamid plus docetaxel represent the standard therapeutic approach in metastatic hormone-sensitive prostate cancer (mHSPC). Patients with low-risk prostate cancer also benefit from additional radiation therapy or radical prostatectomy in terms of progression-free and overall survival. Despite favorable response rates, basically all patients will develop castration resistant prostate cancer (CRPC) within 2.5 to 4 years. In addition to systemic chemotherapy, second-line hormonal treatment of systemic application of radionuclides such as radium223 or 177Lu-PSMA represent salvage management options. However, nowadays about 50-65% of patients will develop symptoms due to local progression of prostate cancer which is the result of improved oncological outcomes with significantly prolonged survival times due to the new medical treatment options. Management of such symptomatic local progression will become more important in upcoming years so that all uro-oncologists need to be aware of the various surgical management options. Complications of the lower urogenital tract such as recurrent gross hematuria ± bladder clotting and with the necessity for red blood cell transfusions, subvesical obstruction and acute urinary retention, rectourethral or rectovesical fistulas might be managed by palliative surgery such as palliative transurethral resection of the prostate (TURP), radical cystectomy, radical cystoprostatectomy with urinary diversion, and pelvic exenteration. Symptomatic or asymptomatic obstruction of the upper urinary tract might be managed by endoluminal or percutaneous urinary diversion, ureteral reimplantation, ileal ureter replacement, or implantation of the Detour® system (Coloplast GmbH, Hamburg, Germany).

Long-term Outcomes of Bevacizumab and Chemoradiation for Locoregionally Advanced Nasopharyngeal Carcinoma: A Nonrandomized Controlled Trial.

Importance: The long-term outcomes associated with adding bevacizumab, a vascular endothelial growth factor inhibitor, to standard chemoradiation have continued to be favorable for a group of patients with locoregionally advanced nasopharyngeal carcinoma (NPC). Objective: To assess long-term toxic effects and clinical outcomes associated with chemotherapy, radiation therapy (RT), and bevacizumab for NPC. Design, Setting, and Participants: This single-arm phase II nonrandomized controlled trial was conducted by the National Cancer Trials Network group and NRG Oncology (formerly Radiation Therapy Oncology Group), with accrual from December 13, 2006, to February 5, 2009, and data analysis from June 26 to July 1, 2019. The study was conducted at 19 cancer centers with a median (IQR) follow-up of 9.0 (7.7-9.3) years. Included patients were adults (aged ≥18 years) with NPC that was World Health Organization (WHO) histologic grade I to IIb or III, American Joint Committee on Cancer stage IIB or greater, and with or without lymph node involvement. Interventions: Patients received 3 cycles of bevacizumab (15 mg/kg) concurrently with standard cisplatin (100 mg/m2) and RT (69.96 Gy) followed by 3 cycles of adjuvant bevacizumab (15 mg/kg) given concurrently with cisplatin (80 mg/m2) and fluorouracil (1000 mg/m2/d). Main Outcomes and Measures: The primary end point was grade 4 hemorrhage or grade 5 adverse events in the first year. Secondary end points were locoregional progression-free (LRPF) interval, distant metastasis-free (DMF) interval, progression-free survival (PFS), overall survival (OS), and other adverse events. Long-term toxic effects and clinical outcomes were reported due to the limited follow-up in the initial report for this trial and the importance of long-term outcomes when combining bevacizumab with chemoradiation. Results: Among 46 patients with NPC who were enrolled, 44 patients were analyzed (29 males [65.9%]; 23 Asian [52.3%], 2 Black [4.5%], and 16 White [36.4%]; 38 not Hispanic [86.4%]; median [IQR] age, 48.5 [39.0-56.0] years). There were 33 patients with a Zubrod performance status of 0, indicating that they were fully functional and asymptomatic (75.0%); 32 patients with a WHO histologic grade of IIb or III (72.7%); and 39 patients with stage III or IVB disease (88.6%). Among analyzed patients, 42 individuals received radiation therapy of 69.96 Gy or greater (95.5%; dose range, 65.72-70.00 Gy); 30 patients received 3 cycles of cisplatin (68.2%) with RT, and 31 patients received 3 cycles of bevacizumab with RT (70.5%); this was followed by 3 cycles of adjuvant cisplatin in 21 patients (47.7%), fluorouracil in 24 patients (54.5%), and bevacizumab in 23 patients (52.3%). No grade 4 hemorrhage or grade 5 AEs were reported in the first year or thereafter. Late grade 3 AEs occurred in 16 patients (36.4%), including 7 patients with dysphagia (15.9%), 6 patients with hearing impairment (13.6%), and 2 patients with dry mouth (4.5%). The 1- and 5-year rates of feeding tube use were 5 of 41 patients (12.2%) and 0 of 27 patients, respectively. There were 19 patients (43.2%) who progressed or died without disease progression (6 patients with locoregional progression [13.6%], 8 patients with distant progression [18.2%], and 5 patients who died without progression [11.4%]). The 5- and 7-year rates were 79.5% (95% CI, 67.6%-91.5%) and 69.7% (95% CI, 55.9%-83.5%) for OS, 61.2% (95% CI, 46.8%-75.6%) and 56.3% (95% CI, 41.5%-71.1%) for PFS, 74.9% (95% CI, 61.4%-86.6%) and 72.3% (95% CI, 58.4%-84.7%) for LRPF interval, and 79.5% (95% CI,66.4%-90.0%) for both times for DMF interval. Among 13 patients who died, death was due to disease in 8 patients (61.5%). Conclusions and Relevance: In this nonrandomized controlled trial, no grade 4 hemorrhage or grade 5 AEs were reported in the first year or thereafter among patients with NPC receiving bevacizumab combined with chemoradiation. The rate of distant metastasis was low although 89% of patients had stage III to IVB disease, suggesting that further investigation may be warranted.

Assessment of Oncology Patient Engagement and Interest in Virtual Mind-Body Programming: Moving Toward Personalization of Virtual Care.

PURPOSE: Accelerated by the COVID-19 pandemic, the virtual platform has become a prominent medium to deliver mind-body therapies, but the extent to which patients engage in virtual mind-body programming remains unclear. This study aims to assess oncology patient engagement in a virtual mind-body program. METHODS: We surveyed oncology patients enrolled in a live-streamed (synchronous) virtual mind-body program in May 2021. Patients self-reported engagement by weekly attendance. We applied multivariate regression to identify associations of engagement with sociodemographic and clinical factors. As an exploratory analysis, we used machine learning to partition engagement subgroups to determine preferential interest in prerecorded (asynchronous) mind-body therapy videos. RESULTS: Among 148 patients surveyed (response rate: 21.4%), majority were female (94.5%), White (83.1%), age 65 years or older (64.9%), retired (64.2%), and in survivorship (61.8%). Patient engagement ranged from 1 to 13 classes/week (mean [standard deviation]: 4.23 [2.56]) and was higher for female (ß, .82; 95% CI, 0.01 to 1.62), non-White (ß, .63; 95% CI, 0.13 to 1.13), and retired patients (ß, .50; 95% CI, 0.12 to 0.88). The partition model identified three engagement subgroups: employed (low engagers), retired White (intermediate engagers), and retired non-White (high engagers). Particularly, low engagers had preferential interest in meditation videos (odds ratio, 2.85; 95% CI, 1.24 to 6.54), and both low and high engagers had preferential interest in Tai Chi videos (odds ratio, 2.26; 95% CI, 1.06 to 4.82). CONCLUSION: In this cross-sectional study among oncology patients, engagement in virtual mind-body programming was higher for female, non-White, and retired patients. Our findings suggest the need for both synchronous and asynchronous mind-body programming to meet the diverse needs of oncology patients.

Risk Factors for Adverse Events in Patients With Breast, Colorectal, and Lung Cancer.

OBJECTIVE: The aim of the study was to identify risk factors associated with medical errors and iatrogenic injuries during an initial course of cancer-directed treatment. METHODS: In this retrospective cohort study of 400 patients 18 years or older undergoing an initial course of treatment for breast, colorectal, or lung cancer at a comprehensive cancer center, we abstracted patient, disease, and treatment-related variables from the electronic medical record. We examined adverse events (AEs) and preventable AEs by risk factor using the χ2 or Fisher exact tests. We estimated the association between risk factors and the relative risk of an additional AE or preventable AE in multivariable negative binomial regression models with backwards selection (P < 0.1). RESULTS: There were 304 AEs affecting 136 patients (34%) and 97 preventable AEs affecting 53 patients (13%). In multivariable analyses, AEs were overrepresented in those with lung cancer compared with patients with breast cancer (incident rate ratio = 1.9, 95% confidence interval = 1.1-3.2). Nonwhite race (1.6, 1.0-2.6), Hispanic or Latino ethnicity (2.0, 0.9-4.1), advanced disease (1.7, 1.1-2.6), use of each additional class of high-risk nonchemotherapy medication (1.6, 1.3-1.9), and chemotherapy (2.1, 1.3-3.3) were all associated with risk of an additional AE. Preventable AEs were associated with lung cancer (7.4, 2.4-23.2), Hispanic or Latino ethnicity (5.5, 1.7-17.9), and high-risk nonchemotherapy medications (1.5, 1.2-2.0). CONCLUSIONS: Risk factors for AEs among patients with cancer reflected patients' underlying disease, cancer-directed therapy, and high-risk noncancer medications. The association of AEs with ethnicity merits further research. Risk factor models could be used prospectively to identify patients with cancer at increased risk of harm.

68 Ga-PSMA-PET/CT helps to select patients for salvage radical prostatectomy with local recurrence after primary radiotherapy for prostate cancer.

OBJECTIVE: To investigate the diagnostic performance of gallium-68 prostate-specific membrane antigen positron emission tomography/computed tomography (68 Ga-PSMA PET/CT) in patients with recurrent prostate cancer with regard to the presence of lymph node metastases (LNM) and local recurrences after primary radiotherapy. PATIENTS AND METHODS: We retrospectively reviewed 142 patients following salvage radical prostatectomy (sRP), 50 of which had a 68 Ga-PSMA PET/CT performed as a preoperative staging module. Predictive clinical parameters were analysed in a multivariate Cox regression analysis. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) and the accuracy of 68 Ga-PSMA PET/CT were analysed with regard to LNM and local recurrence. RESULTS: In all, 613 lymph nodes were resected in 40 patients and 23 lymph nodes had metastatic deposits in 14 patients. In all patients local recurrence could have been found with 68 Ga-PSMA PET/CT. Sensitivity, specificity, PPV and NPV and accuracy on a per lymph node basis were 34.78% (16.38-57.2%), 100% (99.38-100%), 100%, 97.52% (96.69-98.15%) and 97.55% (96.00-98.62%). For detecting local recurrence, the sensitivity and PPV were both 100% with an accuracy of 100% (92.89-100%). CONCLUSION: 68 Ga-PSMA PET/CT should be the standard imaging in biochemical recurrent prostate cancer. With this imaging module one detects first local recurrence and can detect locoregional and distant metastases more precisely than standard CT and bone scan.

PSA levels, PSA doubling time, Gleason score and prior therapy cannot predict measured uptake of [68Ga]PSMA-HBED-CC lesion uptake in recurrent/metastatic prostate cancer.

AIM: To assess whether clinical prostate cancer (PCA) related factors and therapy status can predict the degree of tracer uptake on [68Ga]PSMA-HBED-CC PET/CT. MATERIALS & METHODS: We retrospectively studied 124 patients with recurrent an/or metastatic PCA who underwent [68Ga]PSMAHBED-CC PET/CT. The maximum standardized uptake value (SUVmax) was determined in the prostate bed as well as in three size categories (≤ 5 mm, > 5-15 mm, > 15 mm) in pelvic lymph node, extrapelvic lymph node, bone and visceral metastases. RESULTS: Significant positive correlations between lesion size and SUVmax were found in pelvic lymph node metastases > 5 -≤15 mm (Spearmans rho = 0.502, p = 0.002) as well as in extrapelvic lymph node metastases5 mm (rho = 0.314, p = 0.033) and > 5 ≤-15 mm (rho = 0.614, p < 0.001). SUVmax tended to be higher in the largest diameter category in each anatomic station than in the middle and lower categories. We were unable to find evidence for a relationship between SUVmax and PSA, PSAdt, Gleason score, androgen deprivation therapy, radiation therapy or chemotherapy status. CONCLUSION: Measured tracer uptake in [68Ga]PSMA-HBED-CC PET/CT in patients with recurrent/metastasized prostate cancer is significantly influenced by lesion size as a result of partial volume effects in the very small lesions. Clinical indicators of aggressive prostate cancer behaviour such as PSA levels, PSA doubling time or the Gleason score of the primary tumour, as well as the androgen deprivation therapy, radiation therapy or chemotherapy status are not related to measured tracer uptake. ZIEL:: Beantwortung der Frage ob klinisch bestimmbare Faktoren und Therapiestatus bei Prostatakarzinom (PCA) eine Vorhersage zur Traceranreicherung in [68Ga]PSMA-HBED-CC PET/CT liefern können.Material & Methoden: 124 Patienten mit rezidiviertem und/oder metastasiertem PCA die [68Ga]PSMA-HBED-CC PET/CT untergingen, wurden retrospektiv untersucht. Der maximum Standardized Uptake Value (SUVmax) wurde in der Prostataloge gemessen sowie in drei Größen-Kategorien ( 5 mm, > 5-15 mm, > 15 mm) in Metastasen in den pelvinen Lymphknoten-, extrapelvinen Lymphknoten-, Knochen- und viszeralen Metastasen. ERGEBNISSE: Signifikant positive Korrelationen zwischen Läsionsgröße und SUVmax wurden in pelvinen Lymphknotenmetastasen > 5 -≤15 mm (Spearmans rho = 0.502, p = 0.002), extrapelvinen Lymphknotenmetastasen5 mm (rho = 0.314, p = 0.033) und > 5 -≤15 mm (rho = 0.614, p < 0.001) gefunden. Für jede anatomische Lokalisation wurde ein höherer Wert SUVmax innerhalb der größten Kategorie verglichen zu mittleren und kleinsten Kategorie gefunden.

Preventable and mitigable adverse events in cancer care: Measuring risk and harm across the continuum.

BACKGROUND: Patient safety is a critical concern in clinical oncology, but the ability to measure adverse events (AEs) across cancer care is limited by a narrow focus on treatment-related toxicities. The objective of this study was to assess the nature and extent of AEs among cancer patients across inpatient and outpatient settings. METHODS: This was a retrospective cohort study of 400 adult patients selected by stratified random sampling who had breast (n = 128), colorectal (n = 136), or lung cancer (n = 136) treated at a comprehensive cancer center in 2012. Candidate AEs, or injuries due to medical care, were identified by trained nurse reviewers over the course of 1 year from medical records and safety-reporting databases. Physicians determined the AE harm severity and the likelihood of preventability and harm mitigation. RESULTS: The 400-patient sample represented 133,358 days of follow-up. Three hundred four AEs were identified for an overall rate of 2.3 events per 1000 patient days (91.2 per 1000 inpatient days and 0.9 per 1000 outpatient days). Thirty-four percent of the patients had 1 or more AEs (95% confidence interval, 29%-39%), and 16% of the patients had 1 or more preventable or mitigable AEs (95% confidence interval, 13%-20%). The AE rate for patients with breast cancer was lower than the rate for patients with colorectal or lung cancer (P ≤ .001). The preventable or mitigable AE rate was 0.9 per 1000 patient days. Six percent of AEs and 4% of preventable AEs resulted in serious harm. Examples included lymphedema, abscess, and renal failure. CONCLUSIONS: A heavy burden of AEs, including preventable or mitigable events, has been identified. Future research should examine risk factors and improvement strategies for reducing their burden.

Variation in use of postoperative chemoradiation following surgery for T1 and T2 oropharyngeal squamous cell carcinoma; National Cancer Database.

BACKGROUND AND OBJECTIVES: Primary surgical treatment of patients with early T-classification (T1-T2) oropharyngeal squamous cell carcinoma (OPSCC) has increased. We sought to determine how often these patients receive postoperative chemoradiation (CRT). METHODS: Patients with T1-T2 OPSCC in the National Cancer Database who underwent primary surgery were evaluated for receipt of postoperative CRT. Postoperative CRT use was examined among patients with high risk factors (positive margins and/or extracapsular spread [ECS]), intermediate risk factors (negative margins, no ECS, and either pT3-4 and/or N2-N3), and no apparent risk factors. RESULTS: Of 4833 patients with T1-T2 OPSCC who underwent primary surgery, 43% had high risk pathologic factors, of whom only 63% received postoperative CRT. Another 31% had no apparent risk factors, of whom 16% nonetheless received postoperative CRT. On multivariable analysis, in addition to tumor and demographic factors, patients treated at community hospitals were more likely to receive postoperative CRT (O.R. 1.41 C.I. 1.18-1.87, P = 0.001). CONCLUSIONS: Variation in postoperative CRT use indicates a lack of consensus and/or knowledge about its benefits and indications. Usage of postoperative CRT regardless of pathologic risk factors suggests an area where future efforts at implementation of best practices may be targeted.

Phase 2 study evaluating the combination of sorafenib and temsirolimus in the treatment of radioactive iodine-refractory thyroid cancer.

BACKGROUND: Patients with recurrent and/or metastatic, radioactive iodine-refractory thyroid carcinoma have limited treatment options. Sorafenib, an oral kinase inhibitor, is approved by the US Food and Drug Administration for the treatment of radioactive iodine-refractory thyroid carcinoma, although it demonstrated low response rates (12.2%) as a single agent in the first-line setting. The objective of the current study was to determine whether adding the mammalian target of rapamycin inhibitor temsirolimus to sorafenib could improve on these results. METHODS: In this single-institution, phase 2 study, 36 patients with metastatic, radioactive iodine-refractory thyroid carcinoma of follicular origin received treatment with the combination of oral sorafenib (200 mg twice daily) and intravenous temsirolimus (25 mg weekly). The receipt of prior systemic treatment with cytotoxic chemotherapy and targeted therapy, including sorafenib, was permitted. The primary endpoint was the radiographic response rate. RESULTS: The best response was a partial response in 8 patients (22%), stable disease in 21 (58%), and progressive disease in 1 (3%). Six patients were not evaluable for a response. Patients who had received any prior systemic treatment had a response rate of 10% compared with 38% of those who had not received prior systemic treatment. One of 2 patients with anaplastic thyroid cancer had an objective response. The progression-free survival rate at 1 year was 30.5%. The most common grade 3 and 4 toxicities associated with sorafenib and temsirolimus included hyperglycemia, fatigue, anemia, and oral mucositis. CONCLUSIONS: Sorafenib and temsirolimus appear to be an active combination in patients with radioactive iodine-refractory thyroid carcinoma, especially in patients who received no prior treatment compared with historic data from single-agent sorafenib. Activity is also observed in patients who previously received sorafenib. This regimen warrants further investigation. Cancer 2017;123:4114-4121. © 2017 American Cancer Society.

Performance of a Trigger Tool for Identifying Adverse Events in Oncology.

PURPOSE: Although patient safety is a priority in oncology, few tools measure adverse events (AEs) beyond treatment-related toxicities. The study objective was to assemble a set of clinical triggers in the medical record and assess the extent to which triggered events identified AEs. METHODS: We performed a retrospective cohort study to assess the performance of an oncology medical record screening tool at a comprehensive cancer center. The study cohort included 400 patients age 18 years or older diagnosed with breast (n = 128), colorectal (n = 136), or lung cancer (n = 136), observed as in- and outpatients for up to 1 year. RESULTS: We identified 790 triggers, or 1.98 triggers per patient (range, zero to 18 triggers). Three hundred four unique AEs were identified from medical record reviews and existing AE databases. The overall positive predictive value (PPV) of the original tool was 0.40 for total AEs and 0.15 for preventable or mitigable AEs. Examples of high-performing triggers included return to the operating room or interventional radiology within 30 days of surgery (PPV, 0.88 and 0.38 for total and preventable or mitigable AEs, respectively) and elevated blood glucose (> 250 mg/dL; PPV, 0.47 and 0.40 for total and preventable or mitigable AEs, respectively). The final modified tool included 49 triggers, with an overall PPV of 0.48 for total AEs and 0.18 for preventable or mitigable AEs. CONCLUSION: A valid medical record screening tool for AEs in oncology could offer a powerful new method for measuring and improving cancer care quality. Future improvements could optimize the tool's efficiency and create automated electronic triggers for use in real-time AE detection and mitigation algorithms.

Detection of recurrent prostate cancer lesions before salvage lymphadenectomy is more accurate with (68)Ga-PSMA-HBED-CC than with (18)F-Fluoroethylcholine PET/CT.

AIM: [(68)Ga]PSMA-HBED-CC ((68)Ga-PSMA) is a novel and promising tracer for highly sensitive combined integrated positron emission tomography and X-ray computed tomography (PET/CT) diagnosis of recurrent prostate cancer (PCA). Our aim was to assess the sensitivity, specificity, positive and negative predictive value (PPV/NPV), and accuracy per lesion, as well as the positive predictive value per patient of (68)Ga-PSMA PET/CT using post-lymphadenectomy histology as a standard, and to compare these values to those obtained in a patient collective scanned using (18)F-Fluoroethylcholine ((18)FEC) PET/CT. METHODS: Thirty eight patients had (18)FEC and 28 patients had (68)Ga-PSMA. We performed a pelvic and/or retroperitoneal lymphadenectomy, if necessary supplemented by resection of locally recurrent lesions in accordance with imaging results. RESULTS: In 30/38 (18)FEC and 23/28 (68)Ga-PSMA patients ≥1 focus of PCA was identified in postsurgical histology, leading to a per-patient PPV of 78.9 % for (18)FEC and 82.1 % for (68)Ga-PSMA. In (18)FEC and (68)Ga-PSMA patients, a total of 378 and 308 lymph nodes and local lesions were removed, respectively. For (18)FEC and (68)for Ga-PSMA, the respective sensitivity (95 % confidence interval) was 71.2 % (64.5-79.6 %) and 86.9 % (75.8-94.2 %), specificity was 86.9 % (82.3-90.6 % ) and 93.1 % (89.2-95.9 %), PPV was 67.3 % (57.7-75.9 %) and 75.7 % (64.0-98.5 %), NPV was 88.8 % (84.4-92.3 %) and 96.6 % (93.5-98.5 %), and accuracy was 82.5 % (78.3-86.8 %) and 91.9 % (88.7 %-95.1 %). CONCLUSION: In the present series Ga-PSMA PET/CT shows a better performance than FEC PET/CT with a significantly higher NPV and accuracy for the detection of locoregional recurrent and/or metastatic lesions prior to salvage lymphadenectomy.

Efficacy of concurrent cetuximab vs. 5-fluorouracil/carboplatin or high-dose cisplatin with intensity-modulated radiation therapy (IMRT) for locally-advanced head and neck cancer (LAHNSCC).

OBJECTIVES: We previously reported inferior outcomes for locally-advanced head and neck squamous cell carcinoma (LAHNSCC) patients treated with concurrent cetuximab vs. high-dose cisplatin with intensity-modulated radiation therapy (IMRT). Prior to FDA approval of cetuximab for LAHNSCC, non-cisplatin eligible patients at our institution received 5-fluorouracil (5FU)/carboplatin. We sought to compare concurrent cetuximab vs. 5FU/carboplatin vs. high-dose cisplatin with IMRT for LAHNSCC. MATERIALS AND METHODS: Retrospective review was performed for LAHNSCC patients treated at Memorial Sloan-Kettering Cancer Center from 11/02 to 04/08 with concurrent cetuximab (n=49), 5FU/carboplatin (n=52), or cisplatin (n=259) and IMRT. Overall survival (OS), locoregional failure (LRF), distant metastasis-free survival, and late toxicity were analyzed using univariate and multivariate analyses. OS analysis was confirmed by propensity score adjustment. RESULTS: Treatment groups were similar with regard to primary tumor site, overall stage, and alcohol and tobacco history. Cetuximab and 5FU/carboplatin patients were older, with lower performance status, more comorbidities, higher T classification, and worse renal function. On multivariate analysis, compared with cisplatin and 5FU/carboplatin, cetuximab was associated with inferior 4-year OS (86.9% vs. 70.2% vs. 40.9%; P<.0001) and 4-year LRF (6.3% vs. 9.7% vs. 40.2%; P<.0001). Late toxicity was highest with 5FU/carboplatin (25.0%) vs. cisplatin (8.0%) vs. cetuximab (7.7%). CONCLUSIONS: Although 5FU/carboplatin patients were sicker and experienced greater toxicity than cisplatin patients, no significant difference was found in all endpoints. In contrast, despite similar pretreatment characteristics, outcomes for cetuximab vs. 5FU/carboplatin were significantly worse. We feel that caution should be used with routine use of cetuximab in the management of LAHNSCC.

A phase II study of pralatrexate with vitamin B12 and folic acid supplementation for previously treated recurrent and/or metastatic head and neck squamous cell cancer.

BACKGROUND: Pralatrexate (Fotolyn(TM); Allos Therapeutics Inc.) is an antifolate dihydrofolate reductase (DHFR) inhibitor. We conducted a phase II study of pralatrexate with folic acid and B12 supplementation in patients with recurrent and/or metastatic head and neck squamous cell cancer (R/M HNSCC). PATIENTS AND METHODS: This was a single-arm, Simon optimal two stage phase II study. Patients with R/M HNSCC previously treated with chemotherapy were eligible. The study was initiated with a dosing schedule of pralatrexate 190 mg/m(2) biweekly on a 4-week cycle with vitamin supplementation. Due to toxicity concerns, the dosing was modified to 30 mg/m(2) weekly for 3 weeks in a 4-week cycle with vitamin supplementation. Radiologic imaging was to be obtained about every 2 cycles. RESULTS: Thirteen subjects were enrolled; 12 were treated. Seven of the twelve patients had previously received ≥2 lines of chemotherapy. The most common grade 3 toxicity was mucositis (3 patients). Seven patients did not complete two cycles of therapy due to progression of disease (4), toxicity (1), death (1), and withdrawal of consent (1). Two deaths occurred: one due to disease progression and the other was an unwitnessed event that was possibly related to pralatrexate. No clinical activity was observed. The median overall survival was 3.1 months. The study was closed early due to lack of efficacy. CONCLUSIONS: Pralatrexate does not possess clinical activity against previously treated R/M HNSCC. Evaluation of pralatrexate in other clinical settings of HNSCC management with special considerations for drug toxicity may be warranted.

Controversies on individualized prostate cancer care: gaps in current practice.

Prostate cancer (PCa) is a heterogeneous disease with a wide spectrum of aggressiveness. Evidence-based guidelines are invaluable but cannot be expected to be extensive enough to provide detailed guidance on the management of all patients. As such, the use of individualized, risk-adapted approaches to the management of PCa is indispensable. However, wide variation in treatment approaches observed for patients in practice suggests that there is an unmet need to improve the individualized approach towards patient care. A holistic approach that encompasses guidelines and evidence-based medicine could be used to guide individualized care for patients with PCa, from first contact through to final outcomes. As a result of an international expert meeting, this paper proposes this approach and highlights some of the factors that can be considered when aiming to identify patients' profiles; individualize treatment; and improve communication between patients and the healthcare teams.

Acupuncture for pain and dysfunction after neck dissection: results of a randomized controlled trial.

PURPOSE: To determine whether acupuncture reduces pain and dysfunction in patients with cancer with a history of neck dissection. The secondary objective is to determine whether acupuncture relieves dry mouth in this population. PATIENTS AND METHODS: Patients at a tertiary cancer center with chronic pain or dysfunction attributed to neck dissection were randomly assigned to weekly acupuncture versus usual care (eg, physical therapy, analgesia, and/or anti-inflammatory drugs, per patient preference or physician recommendation) for 4 weeks. The Constant-Murley score, a composite measure of pain, function, and activities of daily living, was the primary outcome measure. Xerostomia, a secondary end point, was assessed using the Xerostomia Inventory. RESULTS: Fifty-eight evaluable patients were accrued and randomly assigned from 2004 to 2007 (28 and 30 patients on acupuncture and control arms, respectively). Constant-Murley scores improved more in the acupuncture group (adjusted difference between groups = 11.2; 95% CI, 3.0 to 19.3; P = .008). Acupuncture produced greater improvement in reported xerostomia (adjusted difference in Xerostomia Inventory = -5.8; 95% CI, -0.9 to -10.7; P = .02). CONCLUSION: Significant reductions in pain, dysfunction, and xerostomia were observed in patients receiving acupuncture versus usual care. Although further study is needed, these data support the potential role of acupuncture in addressing post-neck dissection pain and dysfunction, as well as xerostomia.

Intensity-modulated radiation therapy for the treatment of oropharyngeal carcinoma: the Memorial Sloan-Kettering Cancer Center experience.

PURPOSE: To review the Memorial Sloan-Kettering Cancer Center's experience in using intensity-modulated radiation therapy (IMRT) for the treatment of oropharyngeal cancer. METHODS AND MATERIALS: Between September 1998 and June 2004, 50 patients with histologically confirmed cancer of the oropharynx underwent IMRT at our institution. There were 40 men and 10 women with a median age of 56 years (range, 28-78 years). The disease was Stage I in 1 patient (2%), Stage II in 3 patients (6%), Stage III in 7 (14%), and Stage IV in 39 (78%). Forty-eight patients (96%) received definitive treatment, and 2 (4%) were treated in the postoperative adjuvant setting. Concurrent chemotherapy was used in 43 patients (86%). Patients were treated using three different IMRT approaches: 76% dose painting, 18% concomitant boost with IMRT in both am and pm deliveries, and 6% concomitant boost with IMRT only in pm delivery. Regardless of the approach, the average prescription dose to the gross tumor planning target volume was 70 Gy, while the average dose delivered to the subclinical volume was 59.4 Gy in the dose painting group and 54 Gy in the concomitant boost group. Percutaneous endoscopic gastrostomy feeding tubes (PEGs) were placed before the beginning of treatment in 84% of the patients. Acute and late toxicity were graded according to the Radiation Therapy Oncology Group (RTOG) radiation morbidity scoring criteria. Toxicity was also evaluated using subjective criteria such as the presence of esophageal stricture, and the need for PEG usage. The local progression-free, regional progression-free, and distant metastases-free rates, and overall survival were calculated using the Kaplan-Meier method. RESULTS: Three patients had persistent locoregional disease after treatment. The 2-year estimates of local progression-free, regional progression-free, distant metastases-free, and overall survival were 98%, 88%, 84%, and 98%, respectively. The worst acute mucositis experienced was Grade 1 in 4 patients (8%), Grade 2 in 27 (54%), and Grade 3 in 19 (38%). Xerostomia decreased with increasing time interval from the end of radiotherapy, and among the patients with at least 9 months of follow-up there was 67% Grade 0-1 and 33% Grade 2 toxicity. Of the 42 patients who required upfront PEG placement, 6 were still using PEG for nutrition at the time of this analysis. Three patients had cervical esophageal strictures, and of these, 1 was still PEG dependent 1 year after treatment. Two of these patients were treated with the IMRT concomitant boost am and pm approach, whereas the other was treated with the dose painting technique. CONCLUSIONS: Intensity-modulated radiotherapy achieved encouraging local control rates in patients with oropharyngeal carcinoma. Treatment toxicity was acceptable even in the setting of concurrent chemotherapy. Long-term follow-up is needed to confirm these preliminary findings.
