Negative Pressure Dressing Versus Conventional Passive Dressing in Pilonidal Surgery: A Randomized Controlled Trial.

INTRODUCTION: Surgically treated pilonidal sinus disease (PSD) has high rates of postoperative wound complications, with surgical wound dehiscence (SWD) rates up to 44%. Negative pressure wound therapy (NPWT) is proposed to reduce rates of SWD for other high risk surgical wounds. Our aim was to investigate whether NPWT would reduce rates of SWD compared to conventional passive (CP) dressings for PSD excisions with off-midline primary closure. Our secondary outcomes included patient quality of life and time taken return to normal activities. METHOD: We performed a prospective, crossover pediatric/adult randomized controlled trial for patients (12-40 y) with PSD, requiring excision and off-midline primary closure. Participants were randomized to receive a CP (Primapore or Opsite) or NPWT (SNAP) dressing. Follow-up occurred on D3, D7, D10, D14 and then weekly until wound healing. Patients were sent a 2-month postoperative online survey to assess quality of life outcomes. RESULTS: Fifty patients were recruited, 25 to NPWT & 25 to CP. Mean age and body mass index were 22.6 ± 6.7 y and 26.1 ± 4.5 kg/m2, respectively. 36/50 (76%) were male. The overall dehiscence rate was 42% (21/50); 12/25 (48%) for NPWT & 9/25 (36%) for CP, P = 0.6. Five deep (≥5 mm) SWDs occurred in each group, P > 0.9. SWD was associated with increased excision dimensions in the NPWT group only, P = 0.03. Median duration to wound healing was equivalent in nondehisced wounds, (CP 21.0 [14.0-29.5] versus NPWT 21.0 [16.0-24.0] days, P = 0.7). There were no differences in mean time to the following: return to school/work (NPWT 26.1 ± 18.2 versus CP 29.3 ± 14.7 d, P = 0.6), sit normally (NPWT 22.3 ± 16.2 versus CP 20.1 ± 9.4 d, P = 0.7), or return to physical activity (NPWT21.6 ± 17.2 versus CP40.3 ± 2.4 d, P = 0.2). CONCLUSIONS: NPWT did not improve outcomes after excision of PSD with off-midline primary closure. Despite the limited population size, our results do not support its use as a routine preventative measure.

Tissue adhesive, adhesive tape, and sutures for skin closure of paediatric surgical wounds: prospective randomized clinical trial.

BACKGROUND: Tissue adhesive, adhesive tape, and sutures are used to close surgical incisions. However, it is unclear which produces the best results in children, and whether combination wound closure is better than sutures alone. METHODS: In this parallel randomised controlled trial (ANZCTR: ACTRN12617000158369), children (aged 18 years or less) undergoing elective general surgical or urological procedures were randomized to skin closure with sutures alone, sutures and adhesive tape, or sutures and tissue adhesive. Participants were assessed 2 weeks, 6 weeks, and more than 6 months after operation. Outcomes included wound cosmesis (clinician- and parent-rated) assessed using four validated scales, parental satisfaction, and wound complication rates. RESULTS: 295 patients (333 wounds) were recruited and 277 patients (314 wounds) were included in the analysis. Tissue adhesive wounds had poorer cosmesis at 6 weeks: median 10-point VAS score 7.7 with sutures alone, 7.5 with adhesive tape, and 7.0 with tissue adhesive (P = 0.014). Respective median scores on a 100-point VAS were 80.0, 77.2, and 73.8 (P = 0.010). This difference was not sustained at over 6 months. There was no difference in parent-rated wound cosmesis at 6 weeks (P = 0.690) and more than 6 months (P = 0.167): median score 9.0 with sutures alone, 10.0 with adhesive tape, and 10.0 with tissue adhesive at both stages. Parental satisfaction was similar at all points, with a median score of 5 (very satisfied) for all groups. There was one instance of wound dehiscence in the tissue adhesive group and no wound infections. CONCLUSION: Short-term wound cosmesis was poorer with tissue adhesive although it is unclear whether this difference is sustained in the long-term. There were no differences between techniques for the study outcomes.

Effect of contrast medium on treatment modalities planned with different photon beam energies: a planning study.

BACKGROUND: Routinely, patient's planning scans are acquired after administration of iodinized contrast media but they will be treated in the absence of that. Similarly, high energy photons have a better penetrating power, while low energy photons will result in tighter dose distribution and negligible neutron contamination. The aim of the study was to investigate a suitable photon beam energy in the presence of intravenous contrast medium. MATERIALS AND METHODS: An indigenously made original-contrast (OC) phantom was mentioned as virtual-contrast (VC) and virtual-without-contrast (VWC) phantom were generated by assigning the Hounsfield Units (HU) to different structures. Intensity-modulated (IMRT) and volumetric-modulated-arc (VMAT) plans were generated as per criteria of the TG-119 protocol. RESULTS: It was observed that the maximum dose to the spinal cord was better with 6 mega-voltage (MV) in IMRT. The coverage of Prostate PTV (PR PTV) was similar with all the photon energies and was comparable with TG-119, except for original-contrast (OC) phantom using the VMAT technique. Homogeneity-index (HI) was comparatively better for VMAT plans. CONCLUSION: The contrast CT images lower the dose to targets. IMRT or VMAT plans, generated on such CT images will be delivered with higher doses than evaluated. However, the overdose remains non-significant.

Tumour volumes: Predictors of early treatment response in locally advanced head and neck cancers treated with definitive chemoradiation.

AIM: To analyse and predict early response 3 months post definitive chemoradiation (CCRT) utilising tumour volume (TV) measurement in locally advanced head and neck cancers (LAHNC). BACKGROUND: LAHNC are 3-dimentional lesions. The largest diameter of these tumours measured for T-classification may not necessarily reflect the true tumour dimensions. TV accurately reflects the tumour burden because it is a measurement of tumour burden in all three dimensions. MATERIALS AND METHODS: It is a single institutional prospective study including 101 patients with LAHNC treated with definitive CCRT. TV data noted were primary tumour volume (PTV), total nodal volume (TNV) and total tumour volume (TTV). Response evaluation was done at 3 months after the completion of definitive CCRT and patients were categorised either having achieved complete response (CR) or residual disease. RESULTS: Patients who had not achieved CR were found to have larger TV compared with those who had achieved CR. There were significant inverse correlations between PTV and response (median 16.37 cm(3) vs. 45.2 cm(3); p = 0.001), and between TTV and response (median 36.14 cm(3) vs. 66.06 cm(3); p < 0.001). Receiver operating characteristic (ROC) analysis identified an "optimal cut-off" value of 41 cm(3) for PTV and 42 cm(3) for TTV above and below which the magnitude of difference in response was the greatest. CONCLUSIONS: If response evaluation 3 months post CCRT is to be predicted it is simply not enough to measure the largest single dimension of the tumour. TV seems to be a better and more accurate reflection of the true total tumour burden or extent of the disease.

Myxofibrosarcoma of Head and Neck Region - A Rare Case Report.

Myxofibrosarcoma (MFS) is a rare subtype of soft tissue sarcoma that usually occurs in the extremities of the body. Its location in the head and neck region is unique. Surgery is the primary treatment for all non-metastatic MFS. It has high rates of local recurrence and metastasis. Like other soft tissue sarcomas, the aim of adjuvant treatment is to decrease the chances of local recurrence or metastasis in MFS. Due to its rarity, there is a lack of data showing the benefit of adjuvant treatment in MFS of the head and neck region. We are presenting a case report and literature review on MFS in the head and neck.

Is it too early to recommend local treatment in oligometastatic non-small cell lung cancer: a plea for equipoise.

Oligometastatic non-small cell lung cancer (OMD NSCLC) has been proposed to bridge the spectrum between non-metastatic and widely metastatic states and is perceived as an opportunity for potential cure if removed. Twelve clinical trials on local treatment have been reported, yet none are conclusive. These trials informed the development of a joint clinical practice guideline by the American & European Societies for Radiation Oncology, which endorses local treatment for OMD NSCLC. However, the heterogeneity between prognostic factors within these trials likely influenced outcomes and can only support guidance at this time. Caution against an uncritical acceptance of the guideline is discussed, as strong recommendations are offered based on expert opinion and inconclusive evidence. The guideline is also examined by a patient's caregiver, who emphasizes that uncertain evidence impedes shared decision making.

Outcome following the surgical management of varicocele in children and adolescents: a systematic review and meta-analysis.

Background: The ideal surgical approach for the management of varicocele in children and adolescents remains controversial. Several techniques are available including artery- or lymphatic-sparing with optical magnification (via open inguinal or sub-inguinal approach), laparoscopic, antegrade and retrograde embolization/sclerotherapy. Objectives: We aimed to appraise the clinical outcomes of these techniques in children and adolescents. Data Sources and Methods: A systematic review was conducted (1997-2023). Meta-analysis or proportional meta-analysis for non-comparative studies (Freeman-Tukey transformation) using the random effects model was conducted. Results are expressed as overall proportion % and 95% confidence interval (CI). Results: We identified 1910 studies; 632 duplicates were removed, 1278 were screened, 203 were reviewed and 56 were included, with 12 reporting on 2 different techniques (total of 68 data sets). Optical magnification via inguinal approach (498 cases): recurrence 2.5% (0.6-5.6), hydrocele 1.6% (0.47-3.4), testicular atrophy 1% (0.3-2.0), complications 1.1% (0.2-2.6); optical magnification via sub-inguinal approach (592 cases): recurrence 2.1% (0.7-4.4), hydrocele 1.26% (0.5-2.3), testicular atrophy 0.5% (0.1-1.3), complications 4% (1.0-8.8). Laparoscopic with mass-ligation/division (1943 cases): recurrence 2.9% (1.5-4.6), hydrocele 11.4% (8.3-14.9); complications 1.5% (0.6-2.9); laparoscopic with lymphatic-sparing (974 cases): recurrence 2.4% (1.5-3.5), hydrocele 1.2% (0.45-3.36), complications 1.2% (0.05-3.9); laparoscopic with artery-sparing (228 cases): recurrence 6.6% (2.3-12.9), hydrocele 6.5% (2.6-12.0). Antegrade embolization/sclerotherapy (403 cases): recurrence 7.6% (5.2-10.4), hydrocele 0.8% (0.17-1.9), technical failure 0.6% (0.1-1.6), complications 4.0% (2.3-6.1); retrograde embolization/sclerotherapy (509 cases): recurrence 6.9% (4.6-9.5), hydrocele 0.8% (0.05-2.5), technical failure 10.2% (4.6-17.6), and complications 4.8% (1.0-11.2). Conclusion: The recurrence rate varies between 2.1% and 7.6% and is higher with the embolization/sclerotherapy techniques. Post-operative hydrocele rate varies between 0.8% and 11.4% and is higher with the laparoscopic mass-ligation/division technique. Testicular atrophy has not been reported with the laparoscopic and embolization/sclerotherapy techniques. The retrograde embolization technique is associated with 10% technical failure (inability to complete the procedure). The laparoscopic lymphatic-sparing technique is characterized by the lowest recurrence rate, incidence of hydrocele and other complications, and no reports of testicular atrophy.

Macroscopic Extranodal Extension In Oral Squamous Cell Carcinoma-A Subgroup With Poor Survival.

BACKGROUND: Oral cancer portends a significant cause of morbidity and mortality worldwide. Cervical lymph node metastasis with extranodal extension (ENE) is associated with a poor prognosis. There has been accumulating evidence regarding the extent of ENE to be associated with prognosis and survival. AIM: This observational study was performed to analyze the prognostic implication of macroscopic and microscopic ENE in metastatic cervical lymph nodes of oral cavity cancer patients. METHODS: A total of 92 oral cavity cancer patients with pathologically detected ENE were included in this study. Both the groups (macroscopic and microscopic ENE) were compared in terms of overall survival and disease-free survival by using Kaplan -Meier. The pattern of failure was determined by Fischer's exact test. Univariate and multivariate analyses were calculated to determine the significant risk factors of death. RESULTS: The 2 years of disease-free survival and overall survival rates for the whole cohort were 51.2% and 53.9% respectively. The 2-year survival rate for the microscopic group (≤2 mm) and macroscopic (>2 mm) was 72.6% and 0% respectively, while the distal failure rate in microscopic ENE group and macroscopic ENE group was 22.22% and 44.83% respectively (p-value = 0.026). CONCLUSIONS: Macroscopic ENE (>2 mm) in oral cavity squamous cell cancer represents an aggressive entity with early regional and distant failure as compared to microscopic ENE (≤2 mm). Thus, macroscopic ENE (>2 mm) warrants a distinct subgroup with special consideration for intensification of treatment. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:588-593, 2023.

Treatment Delay during Radiotherapy of Cancer Patients due to COVID-19 Pandemic.

PURPOSE: To analyze the impact of treatment delay caused by COVID-19 infection on patients scheduled for radiotherapy treatment. METHODS AND MATERIALS: In this descriptive study, we analyzed all patients who were COVID-19 positive during the scheduled radiotherapy course, those who had an infection while on neoadjuvant treatment period, or during surgery before the start of radiation. The study period was from June 2020 to May 2021. A treatment delay was defined as a delay in starting the radiation treatment, a gap during their scheduled radiation treatment, or treatment discontinuation. All patients who had a treatment delay were followed-up till November 2021. RESULTS: The median follow-up time of the study was 13 months. Ninety-four patients were selected for the study who met the inclusion criteria. Seventy-seven patients had a mild COVID-19 infection, while 17 had a moderate to severe illness. Of the entire cohort, 83 patients had a treatment delay. The median treatment delay (MTD) in days was 18 (6 to 47). Amongst those who had a treatment delay, 66 patients were treated with curative intent, of which 51 patients are on follow-up - 34 patients are disease-free (MTD - 18.5, 10 to 43), seven had either a residual disease or locoregional recurrence (MTD - 22, 10 to 32), seven had distant metastasis (MTD - 18, 15 to 47), and three patients died (MTD - 20, 8 to 27). Of three patients who died, only one died of COVID-19-related causes. CONCLUSIONS: Even though the mortality due to COVID-19 infection among those who underwent radiotherapy was low, a treatment delay might have caused adverse treatment outcomes. Longer follow-up of these patients is required to further establish this. It will remain debatable whether it was worth delaying radiotherapy for mild to moderate COVID-19 infection for a significant time to cause a potential cancer treatment failure.

Depth of Invasion as an Independent Predictor of Survival in Patients of Stage III Squamous Cell Carcinoma of the Oral Tongue.

OBJECTIVE: Depth of invasion (DOI) has been incorporated in the new AJCC 8th classification. However, even with this new AJCC classification stage III oral tongue squamous cell carcinoma (OTSCC) remains a heterogenous group. The study aims at finding a discreet group within stage III using DOI as a cut-off of 10 mm. METHODS: The institutional database was reviewed from 2012 to 2018 for postoperative stage III OTSCC patients who subsequently received postoperative radiotherapy. Ninety-six patients matched the inclusion criteria. Two groups were created using a DOI cut-off of 10 mm (superficial and deep groups). The groups were analyzed for overall survival (OS) and relapse-free survival (RFS). RESULTS: The baseline and treatment characteristics were comparable between the groups except for the higher number of extensive surgeries, endophytic configuration, pT3 and, DOI in the deep group. For a median follow-up of 40.5 (range: 4-139) months, the median OS and RFS for the superficial group were not reached. The median OS and RFS for the deep group were 101 (range: 73.7-128.3) and 60 (range: 46.6-73.4) months, respectively. The difference was statistically significant for median RFS (P = .008) and trended toward significance for median OS (P = .066) for the superficial group. Multivariate Cox regression analysis showed DOI cut-off as a significant predictor for RFS but not for OS. CONCLUSION: DOI significantly predicts poor RFS. However, showed a trend toward poor OS. This study hints toward a possibility of sub-dividing stage III OTSCC based on DOI cut-off. LEVEL OF EVIDENCE: 3 (Retrospective cohort study) Laryngoscope, 132:1594-1599, 2022.

Tissue adhesive and adhesive tape for pediatric wound closure: A systematic review and meta-analysis.

BACKGROUND: Tissue adhesive (TiA), adhesive tape (AdT), and sutures can be used to close surgical wounds and lacerations in children. However, it is unclear which technique produces the best results. METHODS: In this prospectively registered study, the PubMed, Ovid MEDLINE, Cochrane Library, Centre for Reviews and Dissemination Database, and ScienceDirect databases were searched. English language studies published between January 1980 and August 2017 evaluating TiA and/or AdT for primary skin closure of surgical wounds or lacerations in patients aged ≤18 years were included. Study endpoints included clinician-rated wound cosmesis and incidence of wound complications. RESULTS: Thirty-one studies were included in the systematic review and 16 studies in the meta-analysis. Amongst heterogeneous studies, AdT yielded marginally better cosmetic outcomes than TiA (p = 0.04). There was no difference in cosmesis between sutured wounds and those closed with TiA (p = 0.2). No difference in overall risk of wound infection or dehiscence was identified when comparing TiA with AdT (p = 0.3), and TiA with sutures (p = 0.9 and 0.3 respectively). CONCLUSIONS: TiA, AdT, and sutures can all be used for wound closure with equivalent risk of wound infection and dehiscence. AdT appears to convey better cosmesis. Further adequately powered studies directly comparing techniques are required. LEVELS OF EVIDENCE: Level IV.

A case report evaluating combined effect of intensity-modulated radiotherapy and deep inspiratory breath-hold for mediastinal lymphoma: A dosimetric analysis.

Excellent survival has been reported after combined modality treatment in bulky mediastinal Hodgkin's lymphoma. Late effects such as cardiac morbidity and secondary cancers have been reported after radiotherapy (RT), especially in young adults. Advanced RT techniques such as deep inspiratory breath-hold (DIBH), intensity-modulated RT (IMRT), and volumetric arc therapy have been used recently to reduce these late effects with encouraging results. We hereby present a case report evaluating combined effect of DIBH and IMRT in a young adult with mediastinal lymphoma.

Surgical wound care: A survey of parental knowledge and expectations.

BACKGROUND: Parents play an integral role in postoperative wound care. Existing parental knowledge is potentially variable. Our aim was to evaluate for any gaps or misconceptions in the parental knowledge base to determine the need for targeted educational programs. METHODS: Parents of children presenting to a tertiary pediatric center were surveyed in the preoperative stage. This consisted of 26 questions relating to wound healing, complications, and postoperative care. Participants were asked to complete the questionnaire for a same-day, clean abdominal procedure with a 2 cm incision to standardize responses. Expert responses from pediatric surgeons were utilized as a benchmark for nominating concordant answers. RESULTS: 200 parents were surveyed. 129 parents (64.5%) had previous experience with surgical wound care. Only 64.5% of parents recognized the most concerning features of wound infection, with 65% of parents correctly identifying when infection is most likely to occur. Parents misjudged the time required before return to school (73.5%) and physical activity (51%). More than half of parents (51.5%) expected postoperative antibiotics to be given. Contrary to our routine surgical practice, 80% and 46% of parents respectively felt that regular dressing changes and application of antiseptics to the wound were necessary postoperatively. CONCLUSIONS: There is a deficit of parental knowledge concerning wound healing in children. Therefore, there is a requirement for standardization of advice provided to parents with regards to wound and dressing care, development of wound complications, antibiotic and antiseptic use, and the timing of return to regular activities. TYPE OF STUDY: Survey. LEVEL OF EVIDENCE: III.

Prognostic factors, failure patterns and survival analysis in patients with resectable oral squamous cell carcinoma of the tongue.

PURPOSE: There is sparse literature on treatment outcomes research on resectable oral tongue squamous cell carcinoma (OTSCC). The aim of this study was to measure the treatment outcomes, explore the failure patterns, and identify the potential clinicopathological prognostic factors affecting treatment outcomes for resectable OTSCC. MATERIALS AND METHODS: It is a retrospective analysis of 202 patients with resectable OTSCC who underwent upfront primary surgical resection followed by adjuvant radiotherapy with or without concurrent chemotherapy if indicated. RESULTS: The median follow-up was 35.2 months (range, 1.2 to 99.9 months). The median duration of locoregional control (LRC) was 84.9 months (95% confidence interval, 67.3-102.4). The 3- and 5-year LRC rate was 68.5% and 58.3%, respectively. Multivariate analysis showed that increasing pT stage, increasing pN stage, and the presence of extracapsular extension (ECE) were significantly associated with poorer LRC. The median duration of overall survival (OS) was not reached at the time of analysis. The 3- and 5-year OS rate was 70.5% and 66.6%, respectively. Multivariate analysis showed that increasing pT stage and the presence of ECE were significantly associated with a poorer OS. CONCLUSION: Locoregional failure remains the main cause of treatment failure in resectable OTSCC. There is scope to further improve prognosis considering modest LRC and OS. Pathological T-stage, N-stage, and ECE are strong prognostic factors. Further research is required to confirm whether adjuvant therapy adds to treatment outcomes in cases with lymphovascular invasion, perineural invasion, and depth of invasion, and help clinicians tailoring adjuvant therapy.

Health-related quality of life assessment for head-and-neck cancer patients during and at 3 months after radiotherapy - A prospective, analytical questionnaire-based study.

INTRODUCTION: Health-related quality of life (HRQoL) is a more specific area of QoL that deals with the evaluation and assessment of the impact of the disease and its treatment-related morbidities on a patient's physical, psychological, and social aspects. The aim of the present study was to assess the HRQoL of patients with head-and-neck cancer (HNCs) during and at 3 months after completion of radiotherapy (RT) by intensity-modulated RT. MATERIALS AND METHODS: This study was a prospective, longitudinal, observational, and self-completed questionnaire-based study that included 120 patients with HNC who underwent intensity-modulated RT. The questionnaire had adequate internal consistency. The questionnaires were given to each patient at the beginning of treatment (pretreatment), weekly visits during the course of RT (at the end of 1st, 2nd, 3rd, 4th, 5th, and 6th week), on the day of completion of RT, and then finally at 3 months after completion of RT. Thus, a total of successive nine time points were assessed. RESULTS AND CONCLUSIONS: One hundred and eleven patients completed the questionnaires at all nine time points. HRQoL usually decreases during treatment and then increases to pretreatment levels by 3 months after treatment. The Quality of Life Questionnaire, Core Module and Quality of Life Questionnaire, Head and Neck Module were found to be both valid and reliable. There was a significant QoL reduction for the patients throughout treatment in relation to functions and symptoms in the treatment of HNC. However, all the functions and most of the symptoms returned to baseline at the 3-month follow-up.

Failure patterns of head and neck squamous cell carcinoma treated with radical radiotherapy by intensity modulated radiotherapy technique using focal volume and dosimetric method.

BACKGROUND: Labeling locoregional failures in head and neck cancer (HNC) as "local" and "regional" becomes incomplete when treating with intensity modulated radiotherapy (IMRT). Target delineation and delivery errors, dose in-homogeneity complicate the assessment of failures. A combination of focal point and dosimetric method might attempt at simplifying failure analysis. METHODS: One hundred eleven patients with locally advanced HNC treated with chemoradiation using IMRT were enrolled. Patients with documented failure had their recurrence volume assessed using focal point and dosimetric method. RESULTS: With a median follow-up of 20 (range 0-39) months and median locoregional control (LRC) of 30 (range 24.8-34.5) months, the patients had a 3-year overall survival and LRC of 70.6% and 48.9%, respectively. Of 39 failures, there were 69.2%, 7.6%, 5.1%, 12.8%, and 5.1% type A, B, C, D, and E, respectively using the focal point and dosimetric method. CONCLUSION: With the current classification, majority of the recurrences were high dose failures suggesting inherent radioresistance. While minority of failures were potentially preventable and needed modifying existing IMRT workflow.

Self-expanding esophageal stents for the management of benign refractory esophageal strictures in children: A systematic review and review of outcomes at a single center.

BACKGROUND: This study aimed to evaluate our outcomes and complication rate following placement of self-expanding esophageal stents in children for the management of refractory esophageal strictures and comparing these to the existing literature. METHODS: Outcomes following placement of stents in consecutive patients under 18 years at a single center from 2003 to 2018 were reviewed. A PRISMA-guided systematic review was conducted identifying studies with 5 or more children evaluating self-expanding stents published from 1975 to 2018. Endpoints for both the retrospective and systematic reviews were the requirement for further intervention and stent-associated complications. RESULTS: 25 patients received 65 stents. There were 12 caustic injury-related strictures (48%), 9 anastomotic strictures (36%), and 4 esophagitis-related strictures (16%). Four patients were lost to follow-up. 19/21 patients (90%) required further intervention, and 8/21 (38%) had esophageal replacement. Nine studies, all case series, were included in the systematic review. 97 patients received 160 stents for esophageal strictures and/or perforation. 36 out of 69 patients (52%) with strictures required no further treatment post-stenting, and 22/29 (76%) of esophageal perforations closed with stenting. CONCLUSIONS: Esophageal stents may have a role as a bridge to definitive surgery and for the management of esophageal leaks, but complete stricture resolution post-stenting is unlikely. TYPE OF STUDY: Treatment Study (Case Series with no Comparison Group) LEVEL OF EVIDENCE: Level IV.

Sinonasal teratocarcinosarcoma treated with surgery followed by volumetric modulated radiotherapy: a case report with review of literature.

Surgical excision along with use of postoperative radiotherapy forms an integral management of sinonasal teratocarcinosarcoma (SNTCS). However, given the rarity of the tumor, no standardised guidelines, dose, technique and target delineation exist especially in the era of modern radiation delivery techniques. This is a case of 55-year-old male diagnosed as SNTCS treated with radical ethmoidectomy followed by volumetric modulated radiotherapy, showing good local control and acceptable toxicity profile.

Randomized controlled study comparing simultaneous modulated accelerated radiotherapy versus simultaneous integrated boost intensity modulated radiotherapy in the treatment of locally advanced head and neck cancer.

OBJECTIVES: Comparison of two fractionation schedules of intensity modulated radiotherapy (IMRT) for locally advanced head and neck cancer - simultaneous integrated boost (SIB-IMRT) and simultaneous modulated accelerated radiotherapy (SMART) boost in terms of toxicity and survival end-point measures. PATIENTS AND METHODS: Sixty patients with locally advanced head and neck cancer were randomized in two treatment arms (SIB-IMRT [control arm] and SMART boost arm [study arm]). In the control arm, patients received 70, 63 and 56 Gy in 35 fractions to clinical target volumes (CTV) 1, 2 and 3, respectively. In the study arm, patients received 60 and 50 Gy to CTV 1 and CTV 3, respectively. Toxicities, progression free survival (PFS) and overall survival (OS) were compared between both arms. RESULTS: Baseline patient-related characteristics were comparable between the arms except for primary site of tumour. No significant differences were noted in acute toxicities between the arms except for fatigue which was statistically higher for control arm. No significant differences in 2-year late toxicities were observed. The median follow-up duration was 25.5 (range, 1.8-39.9) months. The 2-year PFS was 53.3% and 80.0% (p = 0.028) for control and study arm, respectively. The 2-year OS was 60.0% and 86.7% (p = 0.020) in control and study arms, respectively. Multivariate analysis showed clinical stage and site to be significant predictors for OS and PFS, respectively. CONCLUSIONS: The SMART boost technique can be a feasible alternative fractionation schedule that reduces the overall treatment time, maintaining comparable toxicity and survival compared with SIB-IMRT.

The use of adaptive intensity-modulated radiotherapy in the treatment of small-cell carcinoma lung refractory to chemotherapy in a patient with preexisting interstitial lung disease.

This is a case report of a 60-year-old diabetic, hypertensive male with a good performance status and a history of bilateral interstitial lung disease with a left upper lobe lung mass diagnosed to be a Stage IIB mixed small-cell/squamous cell carcinoma which was refractory to carboplatin- and etoposide-based chemotherapy. The patient was then taken up for adaptive intensity-modulated radiotherapy with tighter margin under image guidance with a mid-treatment replanning done at 25#. Acute toxicities were assessed weekly and showed no Grade 3 or more reactions. Pulmonary function test showed no detrimental changes during or after radiation. Response assessment at 12 and 20 weeks showed a partial response with decrease in metabolic activity on serial scans.
