Background Patient reported outcome measurements (PROMs) are emerging as an important component of patient management in the cancer setting, providing broad perspectives on patients’ quality of life and experience. The use of PROMs is, however, generally limited to the context of randomised control trials, as healthcare services are challenged to sustain high quality of care whilst facing increasing demand and financial shortfalls. We performed a systematic review of the literature to identify any oncological benefit of using PROMs and investigate the wider impact on patient experience, in cancers of the pelvic abdominal cavity specifically. Methods A systematic review of the literature was conducted using MEDLINE (Pubmed) and Ovid Gateway (Embase and Ovid) until April 2020. Studies investigating the oncological outcomes of PROMs were deemed suitable for inclusion. Results A total of 21 studies were included from 2167 screened articles. Various domains of quality of life (QoL) were identified as potential prognosticators for oncologic outcomes in cancers of the pelvic abdominal cavity, independent of other clinicopathological features of disease: 3 studies identified global QoL as a prognostic factor, 6 studies identified physical and role functioning, and 2 studies highlighted fatigue. In addition to improved outcomes, a number of included studies also reported that the use of PROMs enhanced both patient-clinician communication and patient satisfaction with care in the clinical setting. Conclusions This review highlights the necessity of routine collection of PROMs within the pelvic abdominal cancer setting to improve patient quality of life and outcomes.

Objective Radiotherapy is a crucial treatment modality for pelvic cancers, but uncertainties persist in defining the clinical target volume (CTV) for the inguinal lymphatic drainage region. Suboptimal CTV delineation may compromise treatment efficacy and result in subpar disease control. This study aimed to investigate and map the distribution of lymph node metastases (LNM) in the groin area to facilitate an improved and detailed CTV definition using 18 F-fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT). Methods Inguinal LNM in patients with biopsy-proven pelvic malignancies were identified using 18 F-FDG PET/CT scan. The longitudinally nearest axial plane was determined based on six typical bony landmarks, and the axial direction relative to the femoral artery of LNM was recorded. The distances from the LNM to the nearest edge of the femoral artery were measured on the axial plane. An optimal margin to cover 95% of LNM was estimated to develop contouring recommendations. Results In this study, 500 positive LNM were identified by 18 F-FDG PET/CT among 185 patients with primary pelvic malignancies. Relative to the femoral artery, lymph nodes were distributed laterally (10:00–11:00, n  = 35), anteriorly (12:00–1:00, n  = 213), and medially (2:00–4: 00, n  = 252). For CTV delineation, the recommended distances from the femoral artery on the SFH were lateral 19 mm, anterior 19 mm, and medial 25 mm; on the SGT were lateral 26 mm, anterior 20 mm, and medial 25 mm; on the SPS were lateral 28 mm, anterior 29 mm, and medial 26 mm; on the IPS were anterior 29 mm and medial 28 mm; on the IIT were anterior 27 mm and medial 27 mm; on the ILT were anterior 25 mm and medial 23 mm. Use interpolation to contour the area between six axial slices, including any radiographically suspicious LNM. Conclusions Using 18 F-FDG PET/CT, we investigated the distribution pattern of inguinal LNM and propose a more comprehensive guideline for inguinal CTV delineation.

Purpose To describe experiences of a 3-month pelvic floor muscle training (PFMT) period, with or without support from a physiotherapist, among females with urinary and/or fecal incontinence after pelvic radiotherapy. Method This qualitative interview study included eleven women (aged 47–83 years) with urinary and/or fecal incontinence after radiotherapy treatment for pelvic cancer (radiotherapy completed 3–60 months ago). The eleven informants were part of a larger randomized controlled intervention study where they practiced PFMT, with or without support from a physiotherapist, for 3 months. The support from a physiotherapist included individual support with biofeedback as well as group training. The women were interviewed individually soon after the completion of the pelvic floor muscle training period, and data were analyzed with qualitative content analysis. Result A structured training program, individual support from a physiotherapist, and strategies to establish a daily workout routine were described as valuable when practicing pelvic floor muscle training. Participating in the study gave a sense of meaningfulness and motivation to practice, partly due to the knowledge of a follow-up after the study period. Group and home training were described as both a facilitator and a barrier to PFMT. The women experienced that PFMT had influenced pelvic floor function in terms of increased pelvic floor strength, reduced urinary and fecal incontinence, and an increased ability to hold urine and feces during urgency. PFMT had a relieving effect on pelvic floor pain, although it also contributed to some increase in pain. The perceived improvement in pelvic muscle function led to decreased anxiety, increased safety, feelings of greater freedom in everyday life, a changed attitude toward physical activity, and improved sexual health. All women expressed an intention to continue practicing PFMT and a desire for information and opportunities for PFMT, under the guidance of a physiotherapist, to be implemented in conventional pelvic cancer rehabilitation and made available to all women after pelvic cancer treatment. Conclusion The women who live with the experience of pelvic cancer experienced PFMT as a meaningful intervention for managing urinary and/or fecal incontinence after pelvic radiotherapy. They considered that information and support from a physiotherapist are essential in pelvic cancer rehabilitation, such as PFMT, and should be offered to all women after pelvic cancer treatment.

Fatigue and diarrhea are the most frequent adverse effects of pelvic radiotherapy, while their etiologies are largely unknown. The aim of this study is to investigate the correlations between fatigue, diarrhea, and alterations in gut microbiota induced by pelvic radiotherapy. During the 5-week treatment of pelvic radiotherapy in 11 cancer patients, the general fatigue score significantly increased and was more prominent in the patients with diarrhea. The fatigue score was closely correlated with the decrease of serum citrulline (an indicator of the functional enterocyte mass) and the increases of systemic inflammatory proteins, including haptoglobin, orosomuoid, α1-antitrypsin and TNF-α. Serum level of lipopolysaccharide (LPS) was also elevated, especially in the patients with diarrhea indicating epithelial barrier breach and endotoxemia. Pyrosequencing analysis of 16S rRNA gene revealed that microbial diversity, richness, and the Firmicutes/Bacteroidetes ratio were significantly altered prior to radiotherapy in patients who later developed diarrhea. Pelvic radiotherapy induced further changes in fecal microbial ecology, some of which were specific to the patients with or without diarrhea. Our results indicate that gut microbial dysbiosis prior to radiation therapy may be exploited to predict development of diarrhea and to guide preventive treatment options. Radiation-induced dysbiosis may contribute to pelvic radiation disease, including mucositis, diarrhea, systemic inflammatory response, and pelvic radiotherapy-associated fatigue in cancer patients.

Introduction: Pelvic exenteration (PEx) was first described in the 1940s as a palliative procedure in managing cervical cancer. Since then, advancements in perioperative care have transformed the options available to patients. This highly morbid procedure now offers a “cure” in a select cohort of patients with locally advanced and recurrent pelvic cancers. The large volume of literature in this field has resulted in a heterogeneity of data reporting, making comparative analysis extremely difficult. As such, we set out to examine the current literature and identify currently reported outcomes to guide development of a core information set (CIS) for data reporting for PEx in non-rectal cancers. Methods: A systematic review was carried out. Studies reporting on outcomes following PEx for advanced and recurrent gynecological, urological, and other non-rectal malignancies were included. Standardized outcomes were extracted and mapped to pre-determined domains. Results: Forty-four studies were found to meet our inclusion criteria. A total of 1735 data elements (DEs) were extracted verbatim, and these were assimilated into 111 standard DEs across nine domains. A wide range of reporting frequencies was observed, with the pathological domain containing the highest overall frequencies of DE reporting. Conversely, patient-reported and functional outcomes were noted to be the domain with the lowest frequency. Conclusions: This review highlights recent trends of increased reporting in the field of PEx and how this had invariably resulted in heterogeneous data reporting. We aim to guide the development of a CIS for reporting in non-rectal pelvic malignancies to help standardize future reporting.

Treatment of pelvic tumors remains challenging due to complex anatomy, poor oncological outcome and high complication rates. We sought to investigate the long-term oncological and surgical outcome of these patients. Between 1980 and 2012, 147 patients underwent surgical treatment for pelvic sarcoma. Histological diagnosis was Chondrosarcoma in 54, Ewing's Sarcoma/PNET in 37, Osterosarcoma in 32 and others in 24 patients. Statistical analysis for the evaluation of oncological and surgical outcome was performed by applying Cox proportional hazards regression and Fine-Gray regression models for competing risk (CR) endpoints. The estimated overall survival (OS) to death was 80%, 45% and 37% at 1, 5 and 10 years, respectively. Univariate analyses revealed a statistically significant unadjusted influence of age age (p = 0.038; HR = 1.01), margin (p = 0.043; HR = 0.51) and grade (p = 0.001; HR = 2.27) on OS. Considering the multivariable model, grade (p = 0.005; HR = 3.04) and tumor volume (p = 0.014; HR = 1.18) presented themselves as independent prognostic factors on OS. CR analysis showed a cumulative incidence for major complication of 31% at 5 years. Endoprosthetic reconstruction had a higher risk for experiencing a major complication (p<0.0001) and infection (p = 0.001). Pelvic resections are still associated with a high incidence of complications. Patients with pelvic reconstruction and high volume tumors are especially at risk. Consequently, a cautious decision-making process is necessary when indicating pelvic reconstruction, although a restrictive approach to pelvic reconstruction is not necessarily reasonable when the other option is major amputation.

BackgroundVisceral pain conducted by sympathetic fibers with pelvic and perineal origin can be treated using ganglion impar (GIB) or Walters’ block in a simple and effective manner. This article aims to evaluate the effectiveness, security, and performance difficulty of GIB in patients with pelvic and perineal oncological pain.MethodsA retrospective study between January 2016 and August 2017. Patients with poorly controlled pelvic oncological pain and patients experimenting opioid side effects in which GIB was performed ambulatory were included. Prognostic GIB was performed, under echographic and fluoroscopic control, with local anesthetic and corticoid. The neurolytic block was performed under fluoroscopic guidance. The technique was performed by the same anesthetist with pain management competence. For statistical analysis, Microsoft Excel 2013® and IBM SPSS Statistics version 22.0 were used.ResultsFifteen patients were included. One patient was excluded. A statistical significant basal pain score reduction was observed ((median of the verbal numerical scale (VNS) 7 (p25 = 7; p75 = 8)) compared with 72 h median VNS 4 ((p25 = 3; p75 = 5.3) p = 0.001, and 3 months (median VNS 4 (p25 = 3, p75 = 7)) p = 0.003 after the procedure. Regarding morphine consumption, a statistically significant reduction was observed 3 months after GIB performance (p = 0.012).Discussion/conclusionGIB is a safe and easy-to-perform technique achieving satisfactory and statistically significant results, regarding pain control improvement and opioid consumption reduction in patients which meet selection criteria. Prospective, randomized studies with more patients are needed for further conclusions.

Background: Pelvic floor muscle (PFM) dysfunction and pain are common complications seen in pelvic cancers including the gynecological and genitourinary systems before and after treatments such as chemotherapy, radiotherapy, and surgeries and may contribute to significant morbidity as the survival rates increase in these patients. Objective: The objective of the clinical trial was to evaluate the effect of transcutaneous electrical nerve stimulation (TENS) and stabilization exercises on pelvic pain in pelvic cancer survivors following multimodal treatment. Materials and Methods: Thirty-one patients including both male and female adults treated for pelvic cancers were recruited in the study. Outcome measures in terms of pain were assessed at baseline and at the end of the study by the visual analog scale and genitourinary pain index (GUPI) scale, abdominal muscle strength by pressure biofeedback unit for transverse abdominal (TrA) muscle, and quality of life (QOL) by functional assessment of cancer therapy general questionnaire. Pelvic stabilization exercises and TENS were administered once daily approximately 30 min during the acute hospitalization. Results: Pelvic stabilization exercises and TENS demonstrated to be effective in ameliorating pelvic pain (P < 0.001) and improving in the GUPI scores of pain, incontinence, increasing strength of TrA musculature (P < 0.001), and improving overall QOL (P < 0.005). Conclusion: The trial suggests that a combination of pelvic stabilization exercises and conventional TENS may be used as a strategic tool to reduce pain and improve PFM strength after multimodal treatments in pelvic cancer survivors in the clinical setup of an Indian Scenario.

A systematic review and meta-analysis were designed to evaluate the efficacy and safety of probiotics for prevention of chemoradiotherapy-induced diarrhea in people with abdominal and pelvic cancer. We searched the Cochrane Library, PubMed, EMBASE and Web of Science up to November 2015. We also hand searched the citation lists of included studies and previously identified systematic reviews to identify further relevant trials. Odds ratio (OR) was used to compare efficacy, and the pooled OR was estimated using a random effects model; heterogeneity was assessed with Cochran’s Q and the Higgins’ I 2 -test. Two reviewers assessed trial quality and extracted data independently. Analysis and bias for each included study were performed using Review Manager 5.2. Nine randomized and placebo-controlled studies ( N =1265 participants) were included for assessing efficacy, of which seven were about radiotherapy and two about chemotherapy. Probiotic groups were compared with control groups with respect to the the incidence of diarrhea, OR=0.47 (95% confidence interval 0.28–0.76; P =0.002). Eleven studies, including 1612 people (873 consuming probiotics and 739 not consuming probiotics), were used for the analysis of safety of probiotics. Of the 11 studies, seven studies had no adverse events (AEs) caused by probiotics, whereas four studies reported varying degrees of AEs in their treatment. Probiotics may have a beneficial effect in prevention of chemoradiotherapy-induced diarrhea generally, especially for Grade⩾2 diarrhea. Probiotics may rarely cause AEs.

Purpose Lower limb lymphedema (LLL) is a common condition after pelvic cancer treatment but few studies have evaluated its effect on the quality of life and its consequences on daily life activities among gynecological cancer survivors. Methods We identified a cohort of 789 eligible women, treated with pelvic radiotherapy alone or as part of combined treatment of gynecological cancer, from 1991 to 2003 at two departments of gynecological oncology in Sweden. As a preparatory study, we conducted in-depth interviews with gynecological cancer survivors and constructed a study-specific questionnaire which we validated face-to-face. The questionnaire covered physical symptoms originating in the pelvis, demographic, psychological, and quality of life factors. In relation to the lymph system, 19 questions were asked. Results Six hundred sixteen (78 %) gynecological cancer survivors answered the questionnaire and participated in the study. Thirty-six percent (218/606) of the cancer survivors reported LLL. Overall quality of life was significantly lower among cancer survivors with LLL. They were also less satisfied with their sleep, more worried about recurrence of cancer, and more likely to interpret symptoms from the body as recurrence. Cancer survivors reported that LLL kept them from physical activity (45 %) and house work (29 %) and affected their ability to partake in social activities (27 %) or to meet friends (20 %). Conclusion Lower limb lymphedema has a negative impact on quality of life among gynecological cancer survivors, affecting sleep and daily life activities, yet only a few seek professional help.
