RESUMO

PURPOSE: The global cervical cancer burden is disproportionately high in low- and middle-income countries (LMICs), and outcomes can be governed by the accessibility of appropriate screening and treatment. High-dose-rate (HDR) brachytherapy plays a central role in cervical cancer treatment, improving local control and overall survival. The American Brachytherapy Society (ABS) and Indian Brachytherapy Society (IBS) collaborated to provide this succinct consensus statement guiding the establishment of brachytherapy programs for gynecological malignancies in resource-limited settings. METHODS AND MATERIALS: ABS and IBS members with expertise in brachytherapy formulated this consensus statement based on their collective clinical experience in LMICs with varying levels of resources. RESULTS: The ABS and IBS strongly encourage the establishment of HDR brachytherapy programs for the treatment of gynecological malignancies. With the consideration of resource variability in LMICs, we present 15 minimum component requirements for the establishment of such programs. Guidance on these components, including discussion of what is considered to be essential and what is considered to be optimal, is provided. CONCLUSIONS: This ABS/IBS consensus statement can guide the successful and safe establishment of HDR brachytherapy programs for gynecological malignancies in LMICs with varying levels of resources.

RESUMO

The RASopathies are genetic syndromes associated with pathogenic variants causing dysregulation of the Ras/mitogen-activated protein kinase (Ras-MAPK) pathway, essential for brain development, and increased risk for neurodevelopmental disorders. Yet, the effects of most pathogenic variants on the human brain are unknown. We examined: (1) How Ras-MAPK activating variants of PTPN11/SOS1 protein-coding genes affect brain anatomy. (2) The relationship between PTPN11 gene expression levels and brain anatomy, and (3) The relevance of subcortical anatomy to attention and memory skills affected in the RASopathies. We collected structural brain MRI and cognitive-behavioral data from 40 pre-pubertal children with Noonan syndrome (NS), caused by PTPN11 (n = 30) or SOS1 (n = 10) variants (age 8.53 ± 2.15, 25 females), and compared them to 40 age- and sex-matched typically developing controls (9.24 ± 1.62, 27 females). We identified widespread effects of NS on cortical and subcortical volumes and on determinants of cortical gray matter volume, surface area (SA), and cortical thickness (CT). In NS, we observed smaller volumes of bilateral striatum, precentral gyri, and primary visual area (d's < -0.8), and extensive effects on SA (d's > |0.8|) and CT (d's > |0.5|) relative to controls. Further, SA effects were associated with increasing PTPN11 gene expression, most prominently in the temporal lobe. Lastly, PTPN11 variants disrupted normative relationships between the striatum and inhibition functioning. We provide evidence for the effects of Ras-MAPK pathogenic variants on striatal and cortical anatomy as well as links between PTPN11 gene expression and cortical SA increases, and striatal volume and inhibition skills. These findings provide essential translational information on the Ras-MAPK pathway's effect on human brain development and function.

RESUMO

Purpose: The purpose of this study was to estimate and incorporate rotational error to translational error for clinical target volume (CTV) to planning target volume (PTV) margin calculations for non-6D couch. Materials and Methods: The study involved cone-beam computed tomography (CBCT) images of the patients who already had treatment in Varian Trilogy Clinac. The different sites studied were brain (70 patients, 406 CBCT images), head and neck (72 patients, 356 CBCT images), pelvis (83 patients, 606 CBCT images), and breast (45 patients, 163 CBCT images). Rotational and translational patient shifts were measured with the help of Varian eclipse offline review. The rotational shift introduces translational shift as it resolved along craniocaudal and mediolateral directions. Both rotational and translational error follow normal distribution and their respective errors were used to calculate CTV-PTV margin using van Herk model. Results: Rotational effect on CTV-PTV margin contribution increases with increase in size of CTV. It also increases with increase in distance between center of mass of CTV and isocenter. These margins were more pronounce in single isocenter supraclavicular fossa-Tangential Breast plans. Conclusions: There is always rotational error in all sites and it causes shift and rotation of the target. Rotational contribution to the CTV-PTV margin depends upon geometric center of CTV and isocenter distance and also on size of CTV. CTV-PTV margins should incorporate rotational error along with transitional error.

RESUMO

Introduction: Palliative care (PC) has been classically synonymous with end-of-life care offered to patients with advanced incurable cancers with an aim to improve their quality-of-life (QoL). However, there is growing evidence to suggest that early integration of PC (EIPC) along with cancer-directed management improves patient-reported outcomes. In this study, we aim to evaluate the impact of EIPC on QoL of cervical cancer patients treated with curative intent. Material and Methods: Patients with locally advanced cervical cancer (stage IB2 to IIIB) having eastern cooperative oncology group (ECOG) performance score 0-2 were randomized into EIPC arm and standard of care arm of concurrent chemoradiation by a computer-generated table of random numbers. QoL was assessed by functional assessment of cancer therapy - general (FACT-G) questionnaire twice in both arms. The first assessment was done prior to starting treatment and second assessment at three months after treatment completion. The mean scores on physical, mental, emotional, social, and functional well-being subscales of FACT-G scale were calculated in both arms, and Wilcoxon test was used to evaluate differences in QoL scores within and in between the arms. This trial was registered with Clinical Trials Registry of India (CTRI) vide CTRI/2017/05/008704. Results: Fifty patients were enrolled in each arm. However, only 42 and 45 patients in EPIC and standard oncological care arm were evaluated in the final analysis. Comparing QoL scores between the two time points in each arm, the mean pre-treatment scores in EIPC arm was significantly higher than post-treatment scores in the domains of physical and emotional well-being, whereas social and functional well-being scores improved significantly after treatment as compared with that as baseline. However, when compared between two arms, the difference of mean scores pre- and post-treatment were almost similar for physical and functional well-being but statistically significant differences were found only in social and emotional well-being scales. Conclusions: Our study is a feasibility study done in an attempt to test the validity of EIPC in cervical cancers. The results are inspiring to conduct robust studies in the future to explore this new domain of integration of palliative services in curable cancers.

RESUMO

BACKGROUND: Successful pregnancy outcome in women with synchronous ovarian and endometrial cancers is very rare. We report successful pregnancy outcome in a young woman managed conservatively for synchronous endometrial and ovarian cancer. CASE PRESENTATION: Thirty years old nulliparous lady presented following exploratory laparotomy, left salpingo-oophorectomy and hysteroscopic polypectomy for left adnexal mass. Histology revealed endometrioid carcinoma of left ovary and moderately differentiated adenocarcinoma in the resected polyp. She underwent staging laparotomy along with hysteroscopy which confirmed above findings without any evidence of further tumor spread. She was treated conservatively with high dose oral progestin (megestrol acetate, 160 mg) and leuprolide acetate 3.75 mg monthly injections for three months along with four cycles of carboplatin and paclitaxel based chemotherapy followed by monthly injection of leuprolide for further three months. After failure of spontaneous conception, she underwent ovulation induction for six cycles along with intrauterine insemination which failed. She underwent in vitro fertilization with donor egg followed by elective cesarean section at 37 weeks of gestation. She delivered a healthy baby of weight 2.7 kg. Intraoperatively 5 × 6 cm right ovarian cyst was found which drained chocolate coloured fluid on puncture and cystectomy was carried out. Histological examination revealed endometrioid cyst of right ovary. Uterus was spared as she wanted to preserve her fertility. She is being followed periodically and is normal nine months following delivery. She is on injection Depot medroxy progesterone acetate once every three months.

RESUMO

PURPOSE: To evaluate overall severe late morbidity (grade ≥3) in patients with locally advanced cervical cancer treated with chemo-radiation therapy and magnetic resonance image guided adaptive brachytherapy within the prospective EMBRACE-I study, and to compare the results with published literature after standard radiograph based brachytherapy (BT). METHODS AND MATERIALS: From 2008 to 2015 the EMBRACE-I study enrolled 1416 patients. Morbidity was assessed (Common Terminology Criteria for Adverse Events version 3.0) every 3 months the 1st year, every 6 months the second and third year, and yearly thereafter and 1251 patients had available follow-up on late morbidity. Morbidity events (grade 3-5) were summarized as the maximum grade during follow-up (crude incidence rates) and actuarial estimates at 3 and 5 years. To compare with the published literature on standard radiograph based BT, Common Terminology Criteria for Adverse Events scores from the EMBRACE-I study were retrospectively converted into a corresponding score in the Radiation Therapy Oncology Group and European Organization for Research and Treatment of Cancer system. RESULTS: In total, 534 severe events occurred in 270 patients; 429 events were grade 3 and 105 were grade 4 events. Actuarial estimates for grade ≥3 gastrointestinal (GI), genitourinary (GU), vaginal and fistula events at 5 years were 8.5% (95% confidence interval [CI], 6.9%-10.6%), 6.8% (95% CI, 5.4%-8.6%), 5.7% (95% CI, 4.3%-7.6%), and 3.2% (95% CI, 2.2%-4.5%), respectively. The 5-year actuarial estimate for organ-related events (GI, GU, vaginal, or fistula) was 18.4% (95% CI, 16.0%-21.2%). The 5-year actuarial estimate when aggregating all G≥3 endpoints (GI, GU, vaginal, fistulas, and non-GI/GU/vaginal) was 26.6% (95% CI, 23.8%-29.6%). Thirteen patients had a treatment-related death, 8 of which were associated with GI morbidity. CONCLUSIONS: This report assesses severe morbidity from the largest prospective study on chemo-radiation therapy and image guided adaptive brachytherapy for locally advanced cervical cancer to date. Severe late morbidity was limited per endpoint and organ category, but considerable when aggregated across organs and all endpoints. The late morbidity results in the EMBRACE-I study compare favorably with published literature on standard radiograph based BT for GI morbidity, vaginal morbidity, and fistulas.

RESUMO

PURPOSE: To report clinical and treatment characteristics, remission and failure patterns, and risk factors for local failure (LF) from the EMBRACE-I study. MATERIALS AND METHODS: EMBRACE-I was a prospective, observational, multicenter cohort study on magnetic resonance imaging-based image-guided adaptive brachytherapy (MR-IGABT) in locally advanced cervical cancer. Treatment consisted of external beam radiotherapy, concurrent chemotherapy, and MR-IGABT. LF was defined as progressive or recurrent disease in the cervix, uterus, parametria, pelvic wall, or vagina. Competing risk analysis was used to estimate local tumor control (LC) and Cox proportional regression models for multivariable analysis and dose-response analysis. RESULTS: One thousand three hundred eighteen patients with a median follow-up of 52 months were available for this analysis. Eighty-one patients had persistent disease 3 months after end of treatment. Of those, 60 patients achieved LC at 6-9 months without further treatment, whereas 21 patients had progressive disease. In addition, 77 patients developed a local recurrence after complete remission comprising a total number of 98 LFs. LFs were located inside the MR-IGABT target volumes in 90% of patients with LF. In multivariable analysis, histology, minimal dose to 90% of high-risk clinical target volume (CTVHR), maximum tumor dimension, CTVHR > 45 cm3, overall treatment time, tumor necrosis on magnetic resonance imaging at diagnosis, uterine corpus infiltration at diagnosis and at MR-IGABT, and mesorectal infiltration at MR-IGABT had significant impact on LF. Dose-response analysis showed that a minimal dose to 90% of 85 Gy to the CTVHR led to 95% (95% CI, 94 to 97) LC 3 years postintervention for squamous cell in comparison to 86% (95% CI, 81 to 90) for adeno/adenosquamous carcinoma histology. CONCLUSION: The present study demonstrates the safety and validity of the GYN GEC-ESTRO/ICRU-89 target concept and provides large-scale evidence for dose prescription and new risk factors for LF in MR-IGABT in locally advanced cervical cancer.

RESUMO

PURPOSE: To quantify the association of persistent morbidity with different aspects of quality of life (QOL) in locally advanced cervical cancer (LACC) survivors. MATERIAL AND METHODS: Longitudinal outcome from the EMBRACE-I study was evaluated. Patient-reported symptoms and QOL were prospectively scored (EORTC-C30/CX24) at baseline and regular follow-ups. Physician-assessed symptoms were also reported (CTCAEv.3). Persistent symptoms were defined if present in at least half of the follow-ups. QOL items were linearly transformed into a continuous scale. Linear mixed-effects models (LMM) were applied to evaluate and quantify the association of persistent symptoms with QOL. Overall QOL deterioration was evaluated by calculating the integral difference in QOL over time obtained with LMM for patients without and with persistent symptoms. RESULTS: Out of 1416 patients enrolled, 741 with baseline and ≥ 3 late follow-ups were analyzed (median 59 months). Proportions of persistent EORTC symptoms ranged from 21.8 % to 64.9 % (bowel control and tiredness). For CTCAE the range was 11.3-28.6 % (limb edema and fatigue). Presence of any persistent symptom was associated with QOL, although with varying magnitude. Role functioning and Global health/QOL were the most impaired aspects. Fatigue and pain showed large differences, with reductions of around 20 % for most of the QOL aspects. Among organ-related symptoms, abdominal cramps showed the largest effect. CONCLUSION: Persistent symptoms are associated with QOL reductions in LACC survivors. Organ-related symptoms showed smaller differences than general symptoms such as fatigue and pain. In addition to optimizing treatment to minimize organ-related morbidity, effort should be directed towards a more comprehensive and targeted morbidity management.

RESUMO

BACKGROUND: Turner syndrome (TS) and Noonan syndrome (NS) are distinct genetic conditions with highly similar physical and neurodevelopmental phenotypes. TS is caused by X chromosome absence, whereas NS results from genetic mutations activating the Ras-mitogen-activated protein kinase signaling pathway. Previous neuroimaging studies in individuals with TS and NS have shown neuroanatomical variations relative to typically developing individuals, a standard comparison group when initially examining a clinical group of interest. However, none of these studies included a second clinical comparison group, limiting their ability to identify syndrome-specific neuroanatomical phenotypes. METHODS: In this study, we compared the behavioral and brain phenotypes of 37 girls with TS, 26 girls with NS, and 37 typically developing girls, all ages 5 to 12 years, using univariate and multivariate data-driven analyses. RESULTS: We found divergent neuroanatomical phenotypes between groups, despite high behavioral similarities. Relative to the typically developing group, TS was associated with smaller whole-brain cortical surface area (p ≤ .0001), whereas NS was associated with smaller whole-brain cortical thickness (p = .013). TS was associated with larger subcortical volumes (left amygdala, p = .002; right hippocampus, p = .002), whereas NS was associated with smaller subcortical volumes (bilateral caudate, p ≤ .003; putamen, p < .001; pallidum, p < .001; right hippocampus, p = .015). Multivariate analyses also showed diverging brain phenotypes in terms of surface area and cortical thickness, with surface area outperforming cortical thickness at group separation. CONCLUSIONS: TS and NS have syndrome-specific brain phenotypes, despite their behavioral similarities. Our observations suggest that neuroanatomical phenotypes better reflect the different genetic etiologies of TS and NS and may be superior biomarkers relative to behavioral phenotypes.

RESUMO

OBJECTIVE: Adult granulosa cell tumors (AGCTs) are rare ovarian malignant neoplasms; their etiopathogenetic mechanisms remain largely unelucidated. Lately, defects in mismatch repair (MMR) have been implicated in the pathogenesis of AGCTs. Demonstration of MMR deficiency in these tumors can help identify patients potentially eligible for immune checkpoint inhibition therapy. The present study was done to explore the role of MMR deficiency in the etiopathogenesis of AGCTs. METHODS: This was a retrospective study conducted on histopathologically confirmed AGCT cases. MMR protein expression was evaluated by immunohistochemistry (IHC) on tissue microarrays using an antibody panel of MSH2, MSH6, MLH1, and PMS2. RESULTS: Of a total of 40 ovarian AGCTs evaluated for MMR deficiency, none demonstrated loss of expression of any of the 4 MMR proteins. CONCLUSIONS: The results of our preliminary study show that there is no association between MMR deficiency with AGCT. Nevertheless, larger multicenter studies are needed to confirm or refute this observation.

RESUMO

PURPOSE: A simple scoring system (T-score, TS) for integrating findings from clinical examination and magnetic resonance imaging (MRI) of the primary tumor at diagnosis has shown strong prognostic capability for predicting local control and survival in locally advanced cervical cancer treated with chemoradiation and MRI-guided brachytherapy (BT). The aim was to validate the performance of TS using the multicenter EMBRACE I study and to evaluate the prognostic implications of TS regression obtained during initial chemoradiation. METHODS AND MATERIALS: EMBRACE I recruited 1416 patients, of whom 1318 were available for TS. Patients were treated with chemoradiation followed by MRI-guided BT. A ranked ordinal scale of 0 to 3 points was used to assess 8 anatomic locations typical for local invasion of cervical cancer. TS was calculated separately at diagnosis (TSD) and at BT (TSBT) by the sum of points obtained from the 8 locations at the 2 occasions. RESULTS: Median TSD and TSBT was 5 and 4, respectively. TS regression was observed in 71% and was an explanatory variable for BT technique (intracavitary vs intracavitary/interstitial) and major dose-volume histogram parameters for BT, such as high-risk clinical target (CTVHR), CTVHR D90 (minimal dose to 90% of the target volume), D2cm3 bladder (minimal dose to the most exposed 2 cm3 of the bladder), and D2cm3 rectum. TS regression (TSBT≤5) was associated with improved local control and survival and with less morbidity compared with patients with TSBT remaining high (>5) despite initial chemoradiation. TS regression was significant in multivariate analysis for both local control and survival when analyzed in consort with already established prognostic parameters related to the patient, disease, and treatment. CONCLUSIONS: TS was validated in a multicenter setting and proven to be a strong multidisciplinary platform for integration of clinical findings and imaging with the ability to quantitate local tumor regression and its prognostic implications regarding BT technique, dose-volume histogram parameters, local control, survival, and morbidity.

RESUMO

Cutaneous metastasis can rarely be the first manifestation of visceral malignancies and is commonly seen in advanced-stage malignancies. It is infrequently seen in patients with ovarian malignancies and may develop either late in the course of the disease or at the initial presentation. Such cases are often associated with poor prognosis, and a prompt, precise tissue diagnosis is essential for appropriate patient management and better clinical outcome. Herein, we present a case of cutaneous metastasis in a young woman with an undiagnosed abdominopelvic mass that was diagnosed as metastatic high-grade serous carcinoma (HGSC) on fine-needle aspiration cytology (FNAC) supplemented by immunocytochemistry (ICC) on the cell block. The index case documents a unique and rare metastatic presentation of ovarian HGSC, as non-Sister Mary Joseph anterior abdominal wall nodule, at the initial presentation. Additionally, it highlights the utility of minimally-invasive FNA combined with ICC in prompt and accurate preoperative diagnosis of an underlying ovarian malignancy.

RESUMO

PURPOSE: The purpose was to evaluate patient- and treatment-related risk factors for physician-assessed and patient-reported gastrointestinal (GI) symptoms after radio(chemo)therapy and image guided adaptive brachytherapy in locally advanced cervical cancer. METHODS AND MATERIALS: Of 1416 patients from the EMBRACE-I study, 1199 and 1002 were prospectively evaluated using physician-assessed (Common Terminology Criteria for Adverse Events [CTCAE]) and patient-reported (European Organization for Research and Treatment of Cancer [EORTC]) GI symptoms, respectively. CTCAE severe grade (grade [G] ≥3) events were pooled according to the location in the GI tract (anus/rectum, sigmoid, and colon/small bowel). CTCAE G ≥2 and EORTC "very much" and "quite a bit" plus "very much" scores (≥ "quite a bit") were analyzed for individual symptoms with Cox regression. Logistic regression was used for persistent G ≥1 and EORTC ≥ "quite a bit" symptoms, defined if present in at least half of follow-ups. RESULTS: The incidence of G ≥3 events was 2.8%, 1.8%, and 2.3% for G ≥3 anus/rectum, sigmoid, and colon/small bowel events, respectively. Among G ≥2 symptoms, diarrhea and flatulence were the most prevalent (8.5% and 9.9%, respectively). Among patient-related factors, baseline morbidity, increasing age, smoking status, and low body mass index were associated with GI symptoms to varying degrees. Among treatment-related factors, rectum D2cm3 and the International Commission on Radiation Units and Measurements recto-vaginal reference point (ICRU RV-RP) correlated with G ≥3 anus/rectum events and moderate/persistent diarrhea, proctitis, bleeding, abdominal cramps, and difficulty in bowel control. Bowel D2cm3 correlated with G ≥3 sigmoid and colon/small bowel events and moderate/persistent diarrhea and flatulence. For external beam radiation therapy (EBRT), prescription dose correlated with G ≥3 anus/rectum, diarrhea, and difficulty in bowel control. Patients with large lymph-node boost (V57Gy) were at higher risk for G ≥3 sigmoid events, moderate/persistent diarrhea, proctitis, and cramps. CONCLUSIONS: The analysis showed that both EBRT and image guided adaptive brachytherapy contribute to GI symptoms after locally advanced cervical cancer treatment. Rectum D2cm3, ICRU RV-RP , and bowel D2cm3 are risk factors for GI morbidity. The risk for various symptoms was lower with an EBRT prescription of 45 Gy than 50 Gy and increased with larger V57Gy.

RESUMO

PURPOSE: To evaluate patient-reported sexual outcomes after chemoradiation therapy and image-guided adaptive brachytherapy for locally advanced cervical cancer in the observational, prospective, multicenter EMBRACE-I study. METHODS AND MATERIALS: Sexual outcomes were assessed prospectively with the European Organization for Research and Treatment of Cancer Qualify of Life Questionnaire (EORTC-QLQ-CX24) at baseline and follow-up. Crude incidence and prevalence rates of sexual activity, vaginal functioning problems (dryness, shortening, tightening, pain during intercourse), and sexual enjoyment were evaluated. Associations between pain during intercourse and vaginal functioning problems or sexual enjoyment were calculated, pooling observations over all follow-ups (Spearman correlation coefficient). In patients who were frequently sexually active (≥50% of follow-ups), the effects of regular hormonal replacement therapy (HRT) on vaginal functioning problems were evaluated (Pearson χ2). RESULTS: The analysis involved 1045 patients with a median follow-up of 50 months. Sexual activity was reported by 22% of patients at baseline and by 40% to 47% of patients during follow-up (prevalence rates). Vaginal functioning problems in follow-up were dryness (18%-21%), shortening (15%-22%), tightening (16%-22%), pain during intercourse (9%-21%), and compromised enjoyment (37%-47%). Pain during intercourse was significantly associated with vaginal tightening (r = 0.544), shortening (r = 0.532), and dryness (r = 0.408) and negatively correlated with sexual enjoyment (r = -0.407). Regular HRT was associated with significantly less vaginal dryness (P = .015), shortening (P = .024), pain during intercourse (P = .003), and borderline higher sexual enjoyment (P = .062). CONCLUSIONS: Vaginal functioning problems are associated with pain and compromised sexual enjoyment. Further effort is required for the primary prevention of vaginal morbidity with dose optimization and adaptation. Secondary prevention strategies, including HRT for vaginal and sexual health after radiation therapy in locally advanced cervical cancer, should be considered and sexual rehabilitation programs should be developed further.

RESUMO

PURPOSE: This study aimed to evaluate patient- and treatment-related risk factors for late persistent fatigue within the prospective, multicenter EMBRACE-I study. METHODS AND MATERIALS: Fatigue was prospectively assessed (Common Terminology Criteria for Adverse Events, version 3) at baseline and during regular follow up in 993 patients with locally advanced cervical cancer after treatment with chemoradiotherapy and magnetic resonance imaging-guided brachytherapy. Risk factors for baseline and late persistent fatigue were evaluated with multivariable logistic regression. Late persistent fatigue was defined when either grade ≥1 or ≥2 was scored in at least half of the follow ups. RESULTS: The median follow-up time was 57 months. Baseline fatigue grade ≥1/≥2 (35.8%/6.3%, respectively) was associated with preexisting comorbidities, World Health Organization performance status, being underweight, severe pain, and tumor volume. Late persistent grade ≥1/≥2 fatigue (36.3%/5.8%, respectively) was associated with patient-related factors (baseline fatigue, younger age, obesity) along with the size of irradiated volumes and the level of radiation doses from external beam radiation therapy (EBRT) and brachytherapy (EBRT: V43Gy, V57Gy; EBRT + brachytherapy: V60Gy equivalent dose in 2-Gy fractions). Large-volume lymph node (LN) boost increased the risk for late persistent fatigue grade ≥2 by 18% and 5% in patients with and without baseline fatigue, respectively, compared with no LN boost. The risk for late persistent fatigue grade ≥1 increased by 7% and 4% with V43Gy <2000 cm³ versus >3000 cm³ in patients with and without baseline fatigue, respectively. Late persistent grade ≥1 fatigue occurred in 13% of patients without late persistent organ-related symptoms (gastrointestinal, genitourinary, and vaginal) versus 34% to 43%, 50% to 58%, and 73% in patients suffering from persistent symptoms involving 1, 2, or 3 organs, respectively. CONCLUSIONS: Late persistent fatigue occurs in a considerable number of patients after chemoradiotherapy, and is associated with patient-related factors, the size of volumes irradiated to intermediate and high EBRT and brachytherapy doses, and other persistent organ-related morbidity. These findings support the importance of ongoing efforts to better tailor the target dose and reduce irradiation of healthy tissue without compromising target coverage, using highly conformal EBRT and brachytherapy techniques.

RESUMO

PURPOSE: To evaluate the clinical outcomes in patients with cervical cancer with limited residual disease at brachytherapy (BT) treated with point-based dose prescription. METHODS: Patients with locally advanced squamous cell carcinoma of the cervix treated with computed tomography (CT)-based intracavitary BT were considered for analysis. Patients with good response to external beam radiotherapy and limited residual disease suitable for intracavitary BT alone were included. Postapplication CT scans were performed before each fraction and individual plans were made for each session. The dose per fraction was 9Gy high dose rate, prescribed to point-A. Two sessions were planned, 1 week apart. The organs at risk were contoured, and cumulative dose-volume histograms were computed. Local control, pelvic control, disease-free survival, and overall survival were evaluated and late toxicities were documented. RESULTS: Four hundred ninety patients were included. Overall, 79.8% had International Federation of Gynecology and Obstetrics (FIGO) stage IB2 to IIB disease and 20.2% had stage III to IVA disease. Median dose at point A (EQD210Gy) was 74.4 Gy (interquartile range [IQR] 72.3-74.5 Gy) and median D2cc (EQD23Gy) for bladder, rectum, and sigmoid were 82.5 Gy (IQR, 65.5-90.8 Gy), 66.5 Gy (IQR, 60.7-75.7 Gy), and 54.1 Gy (IQR, 50.5-77.3 Gy), respectively. At a median follow-up of 62 (IQR, 33-87) months, the 5-year local and pelvic control rates were 90.1% and 88.3%, respectively. The 5-year disease-free survival was 80% and overall survival was 88%. Rates of grade 3-4 bladder and rectosigmoid toxicities were 6.93% and 4.08%, respectively. CONCLUSION: In patients with limited residual disease at BT, point-based dose prescription with CT planning results in good local control and acceptable toxicity. In a resource-constrained setting, patients may be triaged to receive point-based BT or magnetic resonance imaging-guided adaptive BT depending on the extent of residual disease.
