RESUMO

AIM: To analyse the long term swallowing function in head and neck cancer patients and correlate with the dose to midline swallowing structures. BACKGROUND: The use of concurrent chemo radiation (CRT) as the present standard of care resulted in high rates of early and late toxicities. Dysphagia, aspiration, and xerostomia are early as well as late effects of radiation. Not many studies on the dysphagia scores during radiation and follow-up period have correlated dose to the swallowing structures, hence this study. MATERIALS AND METHODS: Histologically proven head and neck cancer patients treated with intensity modulated radiation therapy were accrued in this study. The pharyngeal constrictors, larynx and cervical oesophagus were contoured and labelled as midline swallowing structures. The volume of the midline swallowing structures which were outside the PTV was delineated separately and was given a mean dose constraint of 45 Gy. Dysphagia was assessed at baseline, weekly intervals during irradiation and follow-up at six years. The dose to the structures for swallowing was correlated with degree of dysphagia. RESULTS: There was a gradual increase in the dysphagia grade during the course of radiation. There was a significant recovery of late dysphagia compared to dysphagia during the completion of radiation therapy in patients who received <45 Gy to the swallowing structures (p < 0.0001). CONCLUSION: Giving a constraint to the swallowing structure and limiting it to <45 Gy resulted in earlier recovery of swallowing function resulted in good physical, mental and social well being of the patients when compared to those who received >45 Gy.

RESUMO

BACKGROUND: To evaluate the usage of concurrent chemo-radiotherapy (C-CRT) for the treatment of locally advanced cervical cancer. METHODS: Patients with locally invasive cervical carcinoma diagnosed between January 1, 2004 and December 31, 2012 from the National Cancer Database (NCDB) were included. Outcomes for patients undergoing radiation therapy only, 'RT alone' group were compared to those receiving chemotherapy concurrent with radiation 'C-CRT group'. Trends in utilization of C-CRT and factors associated with the deviation from standard of care were explored. Lastly, the effect of hospital volume on utilization of C-CRT was investigated. RESULTS: A total of 18,164 patients undergoing definitive radiation therapy were available for analysis. Utilization of C-CRT increased from 72.4% in 2004 to 84.3% in 2012 (p-trend<0.001). After adjusting for patient, tumor, and treatment factors, a multivariable logistic regression model revealed increasing age, African-American race, Charlson-comorbidity index of ≥2, Medicaid insurance status, uninsured status, and Stage I disease were each independently associated with the lack of C-CRT. After adjusting for patient characteristics, low volume hospitals were noted to have overall significantly lower rates and greater variation in C-CRT administration. Patients in 'RT alone' group had an overall worse survival rate (adjusted-HR 1.47, 95%CI 1.4-1.56). CONCLUSION: Rates of C-CRT administration varied significantly across hospitals in the United States. Hospitals with a high case volume had higher rates and more consistent patterns of C-CRT administration. Furthermore, we identified independent factors, all of which represent noteworthy health disparities, associated with lower rates of C-CRT administration.

RESUMO

Introduction Chemoradiation (CRT) is the standard of care for the treatment of carcinoma cervix, more benefits of CRT are seen in the early stage as compared to a locally advanced stage. Altered fractionation such as accelerated radiotherapy (ART) in locally advanced carcinoma cervix has not been explored much. Here, we have reported the long-term outcome of ART in comparison to conventional CRT in locally advanced cervical cancer patients. Methods From September 2011 to January 2014, 191 patients with locally advanced squamous cell carcinoma of the uterine cervix, FIGO stage IIB - IIIB were included in this study. They were randomized into two arms: the CRT arm (95 patients) versus the ART arm (96 patients). During external beam radiotherapy (EBRT), the patients in the CRT arm received conventional radiotherapy 50 Gy/25 fractions, 2 Gy/fraction, 5 fractions/week with cisplatin 40 mg/m2/week while patients in the ART arm received 50 Gy/25 fractions, 2 Gy/fraction, 6 fractions per week (Monday to Saturday) radiation alone. This was followed by three insertions of 6.5 Gy per fraction of high dose rate (HDR) brachytherapy at one-week intervals in both arms to keep the total treatment time 50 days in the CRT arm versus 45 days in the ART arm. Results The median follow-up of the study population was 57 months (range: 4-108 months). The patients with no residual disease (NRD) after EBRT and complete response (CR) at first follow-up were statistically less in the ART arm as compared to the CRT arm (30.2% versus 53.7% and 42.7% versus 63.2%; p = 0.006 and p = 0.024, respectively). However, there was no statistical difference in response at six months. High-grade acute toxicities hematological (9.5%) and gastrointestinal (15.8%) were more prevalent in the CRT arm in comparison to the ART arm, with no statistical significance (p>0.05) and Grade 1/2 genitourinary toxicity was significantly higher in the CRT arm. Late toxicities in both groups were equivalent. Recurrence, distant type of recurrence, and time to recurrence were similar in both groups. Five-year rates of overall survival (OS) and disease-free survival (DFS) were 51.2% versus 37.2% (p = 0.087) and 57.1% versus 46.3% (p = 0.223) in the CRT arm versus ART arm, respectively. Conclusion ART is a compelling alternative to concurrent chemoradiotherapy for locally advanced cervical cancer, particularly in patients with significant comorbidities, elderly women, and those in higher stages where concurrent chemotherapy's efficacy diminishes. It should be strongly considered when chemotherapy is contraindicated.

RESUMO

Trastuzumab emtansine (T-DM1) is a novel therapeutic for HER2+ breast cancer patients with residual disease after neoadjuvant chemotherapy. Concurrent radiotherapy (RT) is offered to a subset of patients based on results from the KATHERINE trial which showed a favorable safety profile. With emerging therapies that necessitate concurrent RT, we must closely follow rates of skin toxicity. Our first 35 patients who underwent concurrent T-DM1 treatment with breast/chest wall (CW) ± nodal irradiation are reported. Most patients (22/35) had grade 2+ toxicity and 3 patients had grade 3 toxicities. We add our experience with radiation dermatitis and concurrent T-DM1 to contribute to existing reports.

RESUMO

Craniopharyngiomas are rare epithelial malformations in the sellar or suprasellar regions of the craniopharyngeal ducts. Complete surgical resection is difficult due to the location of the base of the skull and the risk of injury to vital neurological structures. Fractionated radiation is effective in controlling residual tumors, but craniopharyngiomas can progress during treatment. The papillary subtype is driven by BRAF V600E mutations. Treatment with BRAF and MEK inhibitors alone has a response rate of 90% but a median progression-free survival of only 12 months. A 57-year-old female presented in May 2017 with complaints of headaches and blurriness in her right eye. Brain MRI demonstrated a 2 cm suprasellar mass engulfing the right optic nerve and optic chiasm. The patient underwent a transsphenoidal hypophysectomy with pathology consistent with a benign pituitary adenoma. Follow-up imaging in August, however, showed recurrence, and a re-resection was performed which surprisingly demonstrated papillary craniopharyngioma. Due to subtotal resection, the patient elected to proceed with intensity-modulated radiation therapy (IMRT) to the tumor bed in April of 2018 with an intended dose of 5400 cGy. After treatment with 2160 cGy in 12 fractions, the patient experienced visual deterioration and progression of the cystic tumor. The patient underwent another debulking procedure but due to rapid recurrence, an endoscopic transsphenoidal fenestration was performed. On postoperative imaging, a cystic mass was still engulfing the right optic nerve and chiasm. Due to the extended break and limited radiation tolerance of the optic chiasm, we elected to re-treat the tumor with an additional 3780 cGy IMRT in conjunction with one cycle of Taflinar and Mekinist, which was completed in August 2018. The cumulative dose to the optic chiasm was 5940 cGy.The patient had an excellent clinical response to treatment with the improvement of vision in her right eye. A brain MRI on 3/29/2019 demonstrated no residual craniopharyngioma. Four-year follow-on CT scan showed no evidence of tumor recurrence. The patient had preservation of vision and did not suffer any late neurological toxicity or new endocrine deficiency. Surgical resection and radiation were ineffective at treating our patient's craniopharyngioma due to rapid cystic progression. This is the first case report in the literature detailing concurrent radiation therapy with BRAF and MEK inhibitors for papillary craniopharyngioma. Despite a suboptimal dose of radiation, our patient had no tumor recurrence and no late toxicity four years after treatment. This represents a potentially novel treatment strategy in this challenging entity.

RESUMO

PURPOSE: To compare the objective and patient-reported toxicities of concomitant boost radiotherapy (CBRT) and concurrent chemoradiation (CRT) in patients with locally advanced head and neck cancers. METHODS AND MATERIAL: In this prospective study, 46 patients with histologically proven stage III-IVA head and neck cancer were randomly assigned to receive either concurrent chemoradiation to a dose of 66 Gy in 33 fractions over 6.5 weeks with concurrent cisplatin (40 mg/m2 IV weekly; control arm) or accelerated radiotherapy with concomitant boost radiotherapy (study arm) to a dose of 67.5 Gy in 40 fractions in five weeks. Acute toxicity was evaluated using RTOG toxicity criteria. The assessment was done weekly after initiation of treatment, at the first follow-up (six weeks), and at three months. The four main patient-reported symptoms of pain, hoarseness of voice, dryness of mouth, and loss of taste were also compared between the two groups to assess patient quality of life during treatment. RESULTS: The mean treatment duration was 37 days in the CBRT arm and 49 days in the CRT arm. Treatment-related interruptions were less in the study group,17.3% in the study, and 27.2% in the control with insignificant P-value. Grade III laryngeal toxicity was significantly higher in the study group (P=0.029). Other acute grade I-III toxicities (pharyngeal, skin, mucositis, and salivary) were comparable in both CRT and CBRT arms. Grade IV toxicities were seen only in the CBRT arm but were resolved at the first follow-up. Haematological toxicities and renal toxicities were significantly higher in the CRT arm, with significant P-values of 0.0004 and 0.018, respectively. CONCLUSION: In patients with locally advanced head and neck cancer, concomitant boost radiotherapy is well tolerated with acceptable local toxicity and minimal systemic toxicity as compared to conventional chemoradiation. It is a feasible option for patients with locally advanced head and neck cancer not fit for concurrent chemoradiation.

RESUMO

BACKGROUND AND PURPOSE: A prognostic scoring system based on laboratory inflammation parameters, [Hemo-Eosinophils-Inflammation (HEI) index], including baseline hemoglobin level, the systemic inflammatory index and eosinophil count was recently proposed in patients with squamous cell carcinoma of the anus (ASCC). HEI was shown to discriminate disease-free (DFS) and overall (OS) survival in ASCC patients treated with concurrent chemoradiation (CRT). We tested the accuracy of the model on a multicentric cohort for external validation. MATERIALS AND METHODS: Patients treated with CRT were enrolled. The Kaplan-Meier curves for DFS and OS based on HEI risk group were calculated and the log-rank test was used. Cox proportional hazards models were used to assess the prognostic factors for DFS and OS. The exponential of the regression coefficients provided an estimate of the hazard ratio (HR). For model discrimination, we determined Harrell's C-index, Gönen & Heller K Index and the explained variation on the log relative hazard scale. RESULTS: A total of 877 patients was available. Proportional hazards were adjusted for age, gender, tumor-stage, and chemotherapy. Two-year DFS was 77 %(95 %CI:72.0-82.4) and 88.3 %(95 %CI:84.8-92.0 %) in the HEI high- and low- risk groups. Two-year OS was 87.8 %(95 %CI:83.7-92.0) and 94.2 %(95 %CI:91.5-97). Multivariate Cox proportional hazards model showed a HR = 2.02(95 %CI:1.25-3.26; p = 0.004) for the HEI high-risk group with respect to OS and a HR = 1.53(95 %CI:1.04-2.24; p = 0.029) for DFS. Harrel C-indexes were 0.68 and 0.66 in the validation dataset, for OS and DFS. Gonen-Heller K indexes were 0.67 and 0.71, respectively. CONCLUSION: The HEI index proved to be a prognosticator in ASCC patients treated with CRT. Model discrimination in the external validation cohort was acceptable.

RESUMO

Management of triple negative breast cancer (TNBC) that is resistant to chemotherapy remains a challenge. Many studies have investigated the unconventional approach of concurrent chemotherapy with radiation in management of TNBC that is resistant to neoadjuvant anthracycline and taxane containing chemotherapy. Various chemotherapies have been used as radiosensitizers. In this report we summarize the published literature and highlight clinical trials that pertain to management of TNBC.

RESUMO

Management of locally advanced cervix cancer underwent major change 2 decades back when concurrent chemotherapy (CCRT) (with cisplatin alone or in combination) along with definite radiation therapy (external + brachytherapy) was found to be superior compared to radiation alone in a series of randomized trials. Since then CCRT has been the standard treatment approach; this has resulted in 5-year overall survival rate of 66% and disease-free survival (DFS) of 58%. About 30% to 40% of patients with locally advanced cervical cancer continue to have treatment failure. Also, some patients experience early and late side effects of treatment with negative impact on quality of life. To improve the outcome further - recent approaches have explored use of weekly paclitaxel and carboplatin for 4 to 6 weeks as dose dense chemotherapy prior to CCRT, adjuvant chemotherapy after CCRT in high risk patients. For patients with early stage disease (IA2-IIA), short course chemotherapy prior to surgery is associated with improved outcome in many studies. Bevacizumab- an inhibitor of vascular endothelial growth factor - is associated with improved survival. More recently, addition of treatment with immune check inhibitors (to boost the ability of T cells to destroy cancer cells) have improved responses and survival in the treatment of recurrent and metastatic cervical cancer. Whether these and other similar novel agents targeting molecular pathways could be brought in front line treatment along with cytotoxic chemotherapy along with bevacizumab are potential areas of current research.

RESUMO

Glioblastoma, isocitrate dehydrogenase (IDH) wild type, is an aggressive primary brain malignancy with a poor prognosis, despite treatment including surgery, chemotherapy, and radiation therapy. Few patients with glioblastoma develop metastasis outside the neuroaxis, likely due to disease progression in the brain prior to extraneural dissemination. The driving mutations of tumors in patients with extraneural metastases are not well described. In this case, we present a severe case of extraneural metastatic glioblastoma, as well as the genetic mutations of the tumor.

RESUMO

Background: About 30% of new non-small cell lung cancer (NSCLC) cases are diagnosed at a locally advanced stage, which includes a highly heterogeneous group of patients with a wide spectrum of treatment options. The management of stage III NSCLC involves a multidisciplinary team, adequate staging, and a careful patient selection for surgery or radiation therapy integrated with systemic treatment. Methods: This is a single-center observational retrospective and prospective study including a consecutive series of stage III NSCLC patients who were referred to the Veneto Institute of Oncology and University Hospital of Padova (Italy) between 2012 and 2021. We described clinico-pathological characteristics, therapeutic pathways, and treatment responses in terms of radiological response in the entire study population and in terms of pathological response in patients who underwent surgery after induction therapy. Furthermore, we analysed survival outcomes in terms of relapse-free survival (RFS) and overall survival (OS). Results: A total of 301 patients were included. The majority of patients received surgical multimodality treatment (n = 223, 74.1%), while the remaining patients (n = 78, 25.9%) underwent definitive CRT followed or not by durvalumab as consolidation therapy. At data cut-off, 188 patients (62.5%) relapsed and the median RFS (mRFS) of the entire population was 18.2 months (95% CI: 15.83−20.57). At the time of analyses 140 patients (46.5%) were alive and the median OS (mOS) was 44.7 months (95% CI: 38.4−51.0). A statistically significant difference both in mRFS (p = 0.002) and in mOS (p < 0.001) was observed according to the therapeutic pathway in the entire population, and selecting patients treated after 2018, a significant difference in mRFS (p = 0.006) and mOS (p < 0.001) was observed according to treatment modality. Furthermore, considering only patients diagnosed with stage IIIB-C (N = 131, 43.5%), there were significant differences both in mRFS (p = 0.047) and in mOS (p = 0.022) as per the treatment algorithm. The mRFS of the unresectable population was 16.3 months (95% CI: 11.48−21.12), with a significant difference among subgroups (p = 0.030) in favour of patients who underwent the PACIFIC-regimen; while the mOS was 46.5 months (95% CI: 26.46−66.65), with a significant difference between two subgroups (p = 0.003) in favour of consolidation immunotherapy. Conclusions: Our work provides insights into the management and the survival outcomes of stage III NSCLC over about 10 years. We found that the choice of radical treatment impacts on outcome, thus suggesting the importance of appropriate staging at diagnosis, patient selection, and of the multidisciplinary approach in the decision-making process. Our results confirmed that the PACIFIC trial and the following introduction of durvalumab as consolidation treatment may be considered as a turning point for several improvements in the diagnostic-therapeutic pathway of stage III NSCLC patients.

RESUMO

Introduction Squamous cell carcinoma of the oral cavity is one of the top 10 malignancies reported globally. Pakistan has a high incidence of oral cancers due to the prevailing poor lifestyle habits/addictions of Pakistanis, and most patients with squamous cell carcinoma present with stage III or IV locally advanced disease. Recommended guidelines indicate surgery as the mainstay of treatment followed by radiotherapy (RT). The addition of induction chemotherapy before surgery or radiation therapy might improve outcomes with increased locoregional control rates. Methods This was a retrospective cohort study comparing the outcomes between surgery followed by concurrent chemoradiotherapy (CCRT) and induction chemotherapy followed by RT. This study primarily aimed to evaluate progression-free survival (PFS) and determine the toxicity of chemotherapy. Results We found out that the mean PFS among patients undergoing surgery and CCRT and those receiving induction chemotherapy followed by RT were 6.40 (± 2.38) months and 7.6 (± 4.76) months, respectively. Conclusion Induction chemotherapy with docetaxel, cisplatin, and 5-fluorouracil followed by RT shows satisfactory results with acceptable toxicity. However, the results are not statistically significant but support the already published data on this treatment aspect of oral cavity cancers.

RESUMO

PURPOSE: This study is to report clinical outcomes of salvage concurrent chemo-radiation therapy (CCRT) in treating patients with loco-regional recurrence (LRR) following initial complete resection of non-small cell lung cancer. MATERIALS AND METHODS: Between February 2004 and December 2016, 127 patients underwent salvage CCRT for LRR. The median radiation therapy (RT) dose was 66 Gy and clinical target volume was to cover recurrent lesion with margin without elective inclusion of regional lymphatics. Majority of patients (94.5%) received weekly platinum-based doublet chemotherapy during RT course. RESULTS: The median follow-up time from the start of CCRT was 25 months. The median survival duration was 49 months, and overall survival (OS) rates at 2 and 5 years were 72.9% and 43.9%. The 2- and 5-year rates of in-field failure-free survival, distant metastasis free survival, and progression free survival were 82.4% and 73.8%, 50.4% and 39.9%, and 34.6% and 22.3%, respectively. Grade ≥ 3 radiation-related esophagitis and pneumonitis occurred in 14 (11.0%) and six patients (4.7%), respectively. On both univariate and multivariate analysis, higher biologically equivalent dose (BED10) (≥ 79.2 Gy10 vs. < 79.2 Gy10; hazard ratio [HR], 0.431), smaller CTV (≤ 80 cm3 vs. > 80 cm3; HR, 0.403), and longer disease-free interval (> 1 year vs. ≤ 1 year; HR, 0.489) were significantly favorable factors for OS. CONCLUSION: The current study has demonstrated that high dose salvage CCRT focused to the involved lesion only was highly effective and safe. In particular, higher BED10, smaller CTV, and longer disease-free interval were favorable factors for improved survival.

RESUMO

Management of cervical cancer has undergone refinement in the past two decades; concurrent chemo-radiation (CCRT) (with cisplatin alone or in combination) is currently the standard treatment approach for patients with locally advanced disease (FIGO stage IIB-IVA). About 30%-40% of such patients fail to achieve complete response; alternative approaches are needed to improve outcome for them. Treatment with bevacizumab (an inhibitor of vascular endothelial growth factor) along with chemotherapy is associated with improved survival in patients with recurrent or metastatic cervical cancer. Weekly paclitaxel and carboplatin for 4-6 weeks as dose dense chemotherapy prior to CCRT is currently under study in a phase III, multicentric trial. Role of adjuvant chemotherapy after CCRT in patients with positive lymph nodes, larger tumor volume and those with stage III-IVA disease needs further exploration. Novel agents targeting molecular pathways are currently being studied. Recent development of immune check point inhibitors is exciting, results of ongoing studies are awaited with interest.

RESUMO

BACKGROUND: Standard treatment for unresectable stage III non-small-cell lung cancer (NSCLC) is concurrent chemo-radiation (CRT). A regimen of induction carboplatin and gemcitabine followed by CRT was developed at the McGill University Health Centre to prevent delays in treatment initiation. We report the long-term outcomes with this regimen based on a pooled analysis of both protocol patients from a phase II study and nonprotocol patients. METHODS AND MATERIALS: Outcomes and toxicity data were retrieved for 142 patients with stage III NSCLC: 43 patients treated on protocol between January 2003 and November 2004, and 101 patients treated off-protocol between December 2004 and August 2013. Patients received 2 cycles of carboplatin with an area under the curve of 5 intravenously (IV) on day 1 and gemcitabine 1000 mg/m2 IV on days 1 and 8 every 3 weeks, followed on day 50 by CRT, 60 Gy/30 over 6 weeks, concomitantly with 2 cycles of paclitaxel 50 mg/m2 IV and gemcitabine 100 mg/m2 IV on days 1 and 8 every 3 weeks. RESULTS: The median overall survival was 23.2 months. With a median follow-up of 23.8 months, the 3-, 4-, and 5-year overall survival was 38%, 30%, and 26%, respectively. The median and 5-year progression-free survival rates were 12.5 months and 25%, respectively. Rates of grade ≥ 3 hematologic, esophageal, and respiratory toxicity were 20%, 10%, and 10%, respectively. Forty-eight patients received further lines of chemotherapy. CONCLUSION: The present analysis affirms the favorable toxicity profile of this novel induction chemotherapy, without apparent compromise in clinical outcomes, when compared with regimens using immediate concurrent CRT.

RESUMO

OBJECTIVE: Although surgical menopause may increase the risks of osteoporosis, few studies have investigated the influence of chemotherapy and radiation therapy. The aim of this study is to evaluate the effects of treatments for gynecological malignancies on bone mineral density (BMD). METHODS: This study enrolled 35 premenopausal women (15 ovarian cancers (OCs), 9 endometrial cancers (ECs), and 11 cervical cancers (CCs)) who underwent surgical treatment that included bilateral oophorectomy with or without adjuvant platinum-based chemotherapy in OC and EC patients, or concurrent chemo-radiation therapy (CCRT) in CC patients according to the established protocols at the Osaka Medical College Hospital between 2006 and 2008. The BMD of the lumbar spine (L1-L4) was measured by dual-energy X-ray absorptiometry, and urine cross-linked telopeptides of type I collagen (NTx) and bone alkaline phosphatase (BAP) were assessed for evaluation of bone resorption and bone formation respectively. These assessments were performed at baseline and 12 months after treatment. RESULTS: Although the serum BAP was significantly increased only in the CC group, a rapid increase in the bone resorption marker urinary NTx was observed in all groups. The BMD, 12 months after CCRT was significantly decreased in the CC group at 91.9±5.9% (P<0.05 in comparison to the baseline). CONCLUSION: This research suggests that anticancer therapies for premenopausal women with gynecological malignancies increase bone resorption and may reduce BMD, particularly in CC patients who have received CCRT. Therefore, gynecologic cancer survivors should be educated about these potential risks and complications.
