Summary: Background: Effective pain management involves a cycle of continual pain assessment, good pain control strategies, and assessment of a standard quality improvement measures. A validated questionnaire that focuses on the quality of postoperative pain management in pediatric surgical patients and parental satisfaction on pain treatment is lacking. We, therefore, modified the revised American Pain Society Patient Outcome Questionnaire to evaluate the quality of postoperative pain management in a pediatric surgical setting. The primary aim of this study was to validate the modified version of revised American Pain Society Patient Outcome Questionnaire. Methods: Parents whose children aged below 12 years and were scheduled for elective surgery in a teaching hospital, were approached to participate in this survey. The reliability of the modified version of revised American Pain Society Patient Outcome Questionnaire was evaluated using Cronbach's alpha test, while the construct validity was assessed with a principal component analysis using a varimax rotation. The parental satisfaction with pain treatment received was measured. Results: A total of 108 parents completed the questionnaire. The internal consistency of the questionnaire shows a Cronbach's alpha of 0.798. Principal component analysis revealed a four‐factor structure of the 12 items which explained 69.7% of the total variance. The factors are "Interference of sleep and activity," "Pain severity and drowsiness," "Perception of care," and "Adverse effects," respectively. Our study showed that this questionnaire is a valid and reliable measure for "Interference of sleep and activity" and "Pain severity and drowsiness" factors, but not for "Perception of care" and "Adverse effects." The results for "Perception of care" and "Adverse effects," therefore, should be reported as individual items instead of total score. The parental satisfaction with pain treatment given was good (median 8.0; IQR 3.0). Conclusion: The modified version of revised American Pain Society Patient Outcome Questionnaire is a feasible and easy instrument to administer. The questionnaire can be used to obtain feedback from parents about the outcomes and experiences of pain management and is helpful in continuous quality evaluation and improvement in the postoperative care in a pediatric setting.

Background: Concurrent-adjuvant chemoradiotherapy (CRT) became a recommended treatment for locoregionally advanced nasopharyngeal carcinoma (NPC) with the first report of a significant survival benefit from the Intergroup 0099 study. However, data on late toxicities are lacking. Previous reports from the current NPC-9901 trial have raised concerns about a failure to improve overall survival (OS) because of an inadequate impact on distant control and increases in toxicities/noncancer deaths. Validation of the long-term therapeutic ratio is needed.Methods: In this phase 3, randomized trial, patients with nonkeratinizing NPC (stage T1-4/N2-3/M0) were randomly assigned to radiotherapy alone (176 patients) or to CRT (172 patients) with concurrent cisplatin followed by adjuvant cisplatin plus fluorouracil.Results: The early findings of significant improvements in tumor control were maintained: the CRT group achieved significantly higher 10-year overall failure-free (62% vs 50%; P = .01) and progression-free survival rates (56% vs 42%; P = .006) because of superior locoregional control (87% vs 74%; P = .003), whereas the impact on distant control remained insignificant (68% vs 65%; P = .24). The initial differences in toxicities diminished with longer follow-up: 52% versus 47% at 10 years for late toxicities (P = .20), 4.1% versus 2.8% for deaths due to treatment toxicity, and 15.1% versus 13.1% for deaths due to incidental/unknown causes. The OS rate for the CRT group reached statistical superiority at 10 years (62% vs 49%; P = .047).Conclusions: Long-term results have confirmed that CRT can significantly improve OS without excessive late toxicities for patients with regionally advanced NPC. However, more potent therapy is needed for improving distant control, especially for patients with stage IVA/B disease. Cancer 2017;123:4147-4157. © 2017 American Cancer Society.

ABSTRACT Background The purpose of this study was to assess the efficacy and toxicities of reirradiation using intensity-modulated radiotherapy (IMRT) in patients with locally advanced recurrent nasopharyngeal carcinoma (NPC). Methods Thirty-eight patients with consecutive rT3 to rT4 NPC treated between 2005 and 2013 were retrospectively analyzed. Results The 3-year overall survival (OS), progression-free survival (PFS), and local control rate were 47.2%, 17.5%, and 44.3%, respectively. Gross target volume (GTV) D95, GTV D50, and age were all important prognostic factors for OS and PFS, but only GTV D95 was an important determinant for local control. A total of 73.7% patients experienced ≥1 grade 3 late toxicities and 3 patients died of massive epistaxis. Temporal lobe necrosis (TLN) developed sooner with a higher total biological equivalent dose. Conclusion Adequate tumor dose coverage was important for treating rT3 to rT4 NPC. Although late complications were common, treatment-related mortality was solely vascular in nature. Dose constraints of neurologic structures for reirradiation should be revised with the latest information on late toxicities. © 2016 Wiley Periodicals, Inc.

Background: The objective of this study was to develop a nomogram for refining prognostication for patients with nondisseminated nasopharyngeal cancer (NPC) staged with the proposed 8th edition of the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) staging system.Methods: Consecutive patients who had been investigated with magnetic resonance imaging, staged with the proposed 8th edition of the AJCC/UICC staging system, and irradiated with intensity-modulated radiotherapy from June 2005 to December 2010 were analyzed. A cohort of 1197 patients treated at Fujian Provincial Cancer Hospital was used as the training set, and the results were validated with 412 patients from Pamela Youde Nethersole Eastern Hospital. Cox regression analyses were performed to identify significant prognostic factors for developing a nomogram to predict overall survival (OS). The discriminative ability was assessed with the concordance index (c-index). A recursive partitioning algorithm was applied to the survival scores of the combined set to categorize the patients into 3 risk groups.Results: A multivariate analysis showed that age, gross primary tumor volume, and lactate dehydrogenase were independent prognostic factors for OS in addition to the stage group. The OS nomogram based on all these factors had a statistically higher bias-corrected c-index than prognostication based on the stage group alone (0.712 vs 0.622, P <.01). These results were consistent for both the training cohort and the validation cohort. Patients with <135 points were categorized as low-risk, patients with 135 to <160 points were categorized as intermediate-risk, and patients with ≥160 points were categorized as high-risk. Their 5-year OS rates were 92%, 84%, and 58%, respectively.Conclusions: The proposed nomogram could improve prognostication in comparison with the TNM stage group. This could aid in risk stratification for individual NPC patients. Cancer 2016;122:3307-3315. © 2016 American Cancer Society. [ABSTRACT FROM AUTHOR]

Background: An accurate staging system is crucial for cancer management. Evaluations for continual suitability and improvement are needed as staging and treatment methods evolve.Methods: This was a retrospective study of 1609 patients with nasopharyngeal carcinoma investigated by magnetic resonance imaging, staged with the 7th edition of the American Joint Committee on Cancer (AJCC)/International Union Against Cancer (UICC) staging system, and irradiated by intensity-modulated radiotherapy at 2 centers in Hong Kong and mainland China.Results: Among the patients without other T3/T4 involvement, there were no significant differences in overall survival (OS) between medial pterygoid muscle (MP) ± lateral pterygoid muscle (LP), prevertebral muscle, and parapharyngeal space involvement. Patients with extensive soft tissue involvement beyond the aforementioned structures had poor OS similar to that of patients with intracranial extension and/or cranial nerve palsy. Only 2% of the patients had lymph nodes > 6 cm above the supraclavicular fossa (SCF), and their outcomes resembled the outcomes of those with low extension. Replacing SCF with the lower neck (extension below the caudal border of the cricoid cartilage) did not affect the hazard distinction between different N categories. With the proposed T and N categories, there were no significant differences in outcome between T4N0-2 and T1-4N3 disease.Conclusions: After a review by AJCC/UICC preparatory committees, the changes recommended for the 8th edition include changing MP/LP involvement from T4 to T2, adding prevertebral muscle involvement as T2, replacing SCF with the lower neck and merging this with a maximum nodal diameter > 6 cm as N3, and merging T4 and N3 as stage IVA criteria. These changes will lead not only to a better distinction of hazards between adjacent stages/categories but also to optimal balance in clinical practicability and global applicability.

BACKGROUND A current recommendation for locoregionally advanced nasopharyngeal carcinoma (NPC) is conventional fractionated radiotherapy with concurrent cisplatin plus adjuvant cisplatin and fluorouracil (PF). In this randomized trial, the authors evaluated the potential therapeutic benefit from changing to an induction-concurrent chemotherapy sequence, replacing fluorouracil with oral capecitabine, and/or using accelerated rather than conventional radiotherapy fractionation. METHODS Patients with stage III through IVB, nonkeratinizing NPC were randomly allocated to 1 of 6 treatment arms. The protocol was amended in 2009 to permit confining randomization to the conventional fractionation arms. The primary endpoint was progression-free survival. Secondary endpoints included overall survival and safety. RESULTS In total, 803 patients were accrued, and 706 patients were randomly allocated to all 6 treatment arms. Comparisons of induction PF versus adjuvant PF did not indicate a significant improvement. Unadjusted comparisons of induction cisplatin and capecitabine (PX) versus adjuvant PF indicated a favorable trend in progression-free survival for the conventional fractionation arm ( P = .045); analyses that were adjusted for other significant factors and fractionation reflected a significant reduction in the hazards of disease progression (hazard ratio [HR], 0.54; 95% confidence interval [CI], 0.36-0.80) and death (HR, 0.42; 95% CI, 0.25-0.70). Unadjusted comparisons of induction sequences versus adjuvant sequences did not reach statistical significance, but adjusted comparisons indicated favorable improvements by induction sequence. Comparisons of induction PX versus induction PF revealed fewer toxicities (neutropenia and electrolyte disturbance), unadjusted comparisons of efficacy were statistically insignificant, but adjusted analyses indicated that induction PX had a lower hazard of death (HR, 0.57; 95% CI, 0.34-0.97). Changing the fractionation from conventional to accelerated did not achieve any benefit but incurred higher toxicities (acute mucositis and dehydration). CONCLUSIONS Preliminary results indicate that the benefit of changing to an induction-concurrent sequence remains uncertain; replacing fluorouracil with oral capecitabine warrants further validation in view of its convenience, favorable toxicity profile, and favorable trends in efficacy; and accelerated fractionation is not recommended for patients with locoregionally advanced NPC who receive chemoradiotherapy.

Introduction Methods Results Conclusion This study aims to establish, execute, and assess the effectiveness of a perioperative enhanced recovery after surgery (ERAS) clinical care pathway in breast reconstruction patients with LD flap breast cancer treatment. The goal is to improve early recovery outcomes, reduce hospitalization time, and enhance patient satisfaction by implementing a standardized approach to postoperative care.This study was conducted at the University of Malaya Medical Center. The outcomes of 21 breast cancer patients who underwent autologous reconstructive breast surgery with the latissimus dorsi (LD) flap within six months before the implementation of the ERAS pathway (pre‐ERAS) were compared with 26 patients who underwent the same surgery with the ultrasound‐guided erector spinae plane (ESP) block for the (ERAS protocol implementation) cohort. The study was conducted from November 2019 to October 2020. The length of hospital stay, amount of analgesic usage, and incidence of postoperative nausea vomiting (PONV) were recorded.The implementation of the ERAS clinical care pathway resulted in shorter hospital stays compared with the preceding care. On average, ERAS patients were mostly discharged on Day 2 post‐surgery, whereas pre‐ERAS patients were mostly discharged on Day 7. ERAS patients had a lower incidence of PONV from Days 1 to 5, starting with 88.5% not experiencing the condition on Days 1 and 2 and increasing to 100% on Day 5. All pre‐ERAS patients experienced PONV in the first 5 days post‐surgery. Fewer ERAS patients required antiemetics post‐surgery (88.5%) compared with pre‐ERAS patients (42.9%).The implementation of the ERAS protocol as part of clinical care in autologous reconstructive breast surgery with the LD flap can improve recovery by shortening hospital stay, decreasing the use of analgesia, and alleviating PONV.
