RESUMO
INTRODUCTION: The study examined whether increased physical activity (PA) in nonmetropolitan cancer survivors was maintained 12 weeks following the PPARCS intervention. METHODS: PA outcomes were assessed using an accelerometer at baseline, end of the intervention, and at 24 weeks. Linear mixed models were used to examine between-group changes in PA outcomes. RESULTS: The increased moderate-to-vigorous PA (MVPA) following intervention was maintained with significantly higher MVPA in the intervention group at 24 weeks (vs. controls) compared to baseline nett change of 52.5 min/week (95% CI 11.0-94.0.4). CONCLUSIONS: Distance-based interventions using wearables and health coaching may produce MVPA maintenance amongst nonmetropolitan cancer survivors.

OBJECTIVE: Interventions to increase physical activity (PA) in cancer survivors have often adopted a "one-size-fits-all" approach and may benefit from being tailored to psychological constructs associated with behavior. The study objective was to investigate the exercise preferences and psychological constructs related to PA among cancer survivors. METHODS: Posttreatment colorectal, endometrial, and breast cancer survivors (n = 183) living in metropolitan and nonmetropolitan areas completed survey measures of PA, exercise preferences, attitudes, self-efficacy, perceived behavioral control (PBC), and intention toward PA. RESULTS: A structural equation model with adequate fit and quality indices revealed that instrumental attitude and self-efficacy were related to PA intention. Intention was related to behavior and mediated the relationship between self-efficacy and behavior. Preferred exercise intensity was related to self-efficacy, PBC, attitudes, and intention, while preferred exercise company was related to self-efficacy and PBC. Participants preferred moderate-intensity PA (71%), specifically self-paced (52%) walking (65%) in an outdoor environment (58%). CONCLUSIONS: Since instrumental attitude and self-efficacy were associated with PA, incorporating persuasive communications targeting attitudes in PA interventions may promote PA participation. As cancer survivors who prefer low-intensity exercise and exercising with others report lower self-efficacy and PBC, interventions targeting confidence and successful experience in this group may also be warranted.

PURPOSE: Cancer survivors are at risk of comorbidities and mortality, and those living outside of metropolitan areas are particularly susceptible given poorer socioeconomic, health and support resources. As engagement in health behaviours is affected by participants' autonomous motives, investigation of the motives of cancer survivors in metropolitan and non-metropolitan areas could elucidate the values and reasons for practising health behaviours, allowing programs to be tailored to these motives. METHODS: Metropolitan (n = 103) and non-metropolitan (n = 80) Australian cancer survivors completed a survey item by describing their motives for physical activity and healthy diet change. Inductive thematic analysis of responses was performed to establish themes across health behaviour motives. RESULTS: Analyses revealed four themes: to be able to, longevity, psychological health and appearance. Survivors primarily referred to being able to enjoy family, leisure activities, travel and staying independent, with these motives often linked to longevity. Motives were similar across locations; however, those in non-metropolitan locations reported continuation of work and pain relief more frequently. Female survivors more often reported weight loss. CONCLUSIONS: A predominant motive for health behaviour change in cancer survivors across geographical location was the ability to enjoy family and engage in leisure and work activities. Programs aiming to promote health behaviours in cancer survivors might consider framing interventions accordingly by emphasizing benefits of longevity and maintaining independence.

BACKGROUND AND OBJECTIVES: Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) offers selected patients with peritoneal surface malignancies (PSM) an improved survival. However, a substantial proportion of patients develop peritoneal recurrence. There is limited data on the efficacy of iterative CRS and HIPEC in such patients. This study evaluates the safety, efficacy and outcomes after re-do CRS and HIPEC for PSM at a tertiary institute. METHODS: Patients undergoing re-do CRS and HIPEC for recurrent PSM were included. Cases were grouped into the first and iterative cases and compared to evaluate differences in morbidity, survival and factors influencing survival. RESULTS: One hundred and forty patients developed peritoneal recurrence after CRS and HIPEC. Thirty-seven patients underwent re-do CRS and HIPEC. The most common indication for iterative surgery was pseudomyxoma peritonei in 27 patients (73.0%). Median survival was 97 months for patients undergoing iterative surgery compared to 40 months for those who did not. Median survival following first and iterative surgery was 97 and 89 months, respectively (p = 0.15). Median progression-free survival after first and iterative surgery was 23 and 19 months, respectively (p = 0.47). At iterative CRS and HIPEC, incomplete cytoreduction (HR 12.82, 95% CI 1.64-100.35), increasing PCI (HR 1.13, 95% CI 1.04-1.22), in particular PCI >20 (HR 10.90, 95% CI 1.37-86.66) were factors associated with worse overall survival. CONCLUSION: In well selected patients, iterative CRS and HIPEC is safe, and can provide favorable survival with low morbidity. Completeness of cytoreduction and PCI are factors that influence overall survival.

BACKGROUND: Peritoneal surface malignancy (PSM) was historically associated with a poor survival. The adoption of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) can now offer patients with PSM a favourable overall survival. Here, we report our single-institute outcomes following CRS and HIPEC for PSM and evaluate changes in our practice over time. METHODS: This is a retrospective review from 2009 to 2018 of all patients undergoing CRS and HIPEC for PSM at a statewide peritoneal disease centre. Cases were divided into the first half and second to compare changes in practice over time. RESULTS: Three hundred and eighty four CRS and HIPEC cases were performed during this time. The median age was 56 years with 59.6% female. The median peritoneal carcinomatosis index (PCI) was 11, with a reduction in PCI in the second cohort (9 v 15, p < 0.01). Complete cytoreduction rates were significantly higher in the second cohort (82.3% v 67.7%, p < 0.01). Overall, grade III/IV complications occurred in 101 cases (26.3%) with three (0.8%) perioperative mortalities. Median overall survival (OS) for the entire cohort was 85 months, with a 5-year survival of 52%. Median OS was 97 months for PMP, 34 months for colorectal peritoneal metastases and 27 months for other histologies. Completeness of cytoreduction, histology type, and PCI were factors independently associated with overall survival. CONCLUSION: CRS and HIPEC can offer highly favourable outcomes for PSM with low morbidity. Successful complete cytoreduction rates improved significantly with greater experience and better patient selection.

BACKGROUND: Physical activity (PA) is important for cancer survivors. Trials of remotely delivered interventions are needed to assist in reaching under-served non-metropolitan cancer survivors. The objective of this study was to ascertain whether wearable technology, coupled with health coaching was effective in increasing PA in breast and colorectal cancer survivors living in regional and remote areas in Australia. METHODS: Cancer survivors from 5 states were randomized to intervention and control arms. Intervention participants were given a Fitbit Charge 2TM and received up to 6 telephone health coaching sessions. Control participants received PA print materials. Accelerometer assessments at baseline and 12 weeks measured moderate-to-vigorous PA (MVPA), light PA, and sedentary behavior. RESULTS: Eighty-seven participants were recruited (ageâ¯=â¯63 ± 11 years; 74 (85%) female). There was a significant net improvement in MVPA of 49.8 min/week, favoring the intervention group (95% confidence interval (95%CI): 13.6-86.1, pâ¯=â¯0.007). There was also a net increase in MVPA bouts of 39.5 min/week (95%CI: 11.9-67.1, pâ¯=â¯0.005), favoring the intervention group. Both groups improved light PA and sedentary behavior, but there were no between-group differences. CONCLUSION: This is the first study to demonstrate that, when compared to standard practice (i.e., PA education), a wearable technology intervention coupled with distance-based health coaching, improves MVPA in non-metropolitan cancer survivors. The results display promise for the use of scalable interventions using smart wearable technology in conjunction with phone-based health coaching to foster increased PA in geographically disadvantaged cancer survivors.

This study examines the cationic polymers 1) guar hydroxypropyltrimonium chloride polymers (GHPTC), 2) acrylamidopropyltrimonium chloride/acrylamide copolymer (APTAC/Acm), 3) polyquaternium polymers (PQ-10, PQ-7, PQ-67), and 4) a new polymer system approach for their a) deposition efficiency (as measured by quantifying oils deposited on virgin hair) and b) ability to deliver good wet and dry lubricity to the hair from a cleansing formulation as measured by comb energy and friction characteristics of the hair samples. Conditioning polymer technology approaches 1) acrylamidopropyltrimonium chloride/acrylamide copolymer, 2) a guar hydroxypropyltrimonium chloride polymer, and 3) the new polymer system approach deliver superior deposition of natural conditioning oils and dimethicone materials from anionic/amphoteric surfactant cleansing formulations. These new polymer technologies offer formulators the ability to improve uniformity of deposition as well as deposition efficiency of conditioning agents onto hair, and target the desired hair lubricity.

Peritoneal metastases confer the worst survival among all sites in patients with metastatic colorectal cancer. They develop largely through transcoelomic spread, with a sequence of events that allow cells to first detach from primary tumours, survive in the peritoneal environment, attach to the peritoneal surface of organs and migrate into the submesothelial space to create a microenvironment conducive to metastatic growth. Diagnostic challenges have previously hindered early identification of peritoneal metastases. While advances in diagnostic modalities have improved our ability to identify peritoneal metastases, lesions under 0.5 cm remain challenging to detect. The advent of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) can offer selected patients with colorectal peritoneal metastases a favourable long-term survival. Recent trials, however, have cast doubts on the efficacy of HIPEC, with the recent PRODIGE 7 trial showing no benefit from oxaliplatin based HIPEC in addition to good quality cytoreductive surgery in resectable disease. While peritoneal recurrence can be reliably predicted from high-risk features in primary tumours such as a perforated cancer, ovarian metastases or T4a cancers, the use of prophylactic second look surgery with HIPEC or adjuvant HIPEC failed to demonstrate any survival benefit in high-risk cases in recent clinical trials, raising further questions about the efficacy of HIPEC. With high failure rates from systemic chemotherapy in unresectable disease, novel surgical techniques such as pressurized intraperitoneal aerolized chemotherapy are being investigated in clinical trials worldwide. Further collaborative research is needed to explore newer avenues of treatment for this poor prognostic cohort.

BACKGROUND: There is great variability in the uptake of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) in the management of colorectal peritoneal metastases (CRPM) in Australia and New Zealand. This study aims to provide a snapshot of perceptions among colorectal surgeons in the management of CRPM. METHODS: A structured ten-question online survey was sent to all colorectal surgeons, with three questions on clinical experience and demographics, one on health economics and six on hypothetical clinical scenarios. Scores were collated and reported based on Likert scales. RESULTS: Eighty-one respondents (36.2%) completed the survey. Most surgeons (66.7%) strongly disagreed with offering CRS and HIPEC at all hospitals. The majority (87.7%) agreed that CRS and HIPEC offered a higher survival benefit than systemic chemotherapy in pseudomyxoma peritonei (PMP), and 69.1% in CRPM (comparators: 60.5% ovarian cancer, 14.8% gastric cancer). There were mixed strategies in managing low-volume, isolated peritoneal recurrences. The majority did not recommend second-look laparoscopy, but favoured operative management of Krukenberg tumours. In the presence of incidental peritoneal metastases, only 29.6% favoured biopsy only and referring the patient to a peritoneal disease centre. CONCLUSIONS: Response rate was relatively low. In Australia and New Zealand, colorectal surgeons see a strong role for CRS and HIPEC in the management of PMP and CRPM. The role of "second look" surgery in high-risk cases is controversial and not supported. Krukenberg tumours are viewed as surgical disease. Regular updates and collaboration with peritoneal centres may help surgeons stay abreast with latest evidence in the field.
RESUMO
PURPOSE: Intra-abdominal desmoid tumors associated with familial adenomatous polyposis are heterogeneous. A recent staging system categorizes desmoids according to size, symptoms, and complications. We applied the staging system to determine whether it separates patients into clinically significant groups. METHODS: The staging system was applied to 101 patients with familial adenomatous polyposis. RESULTS: There were 21 patients with Stage I tumors, 36 with Stage II, 26 with Stage III, and 18 with Stage IV. Twelve patients with Stage I and five with Stage II tumors needed no treatment. Eight patients with Stage I disease received medical treatment, as did 26 with Stage II, 16 with Stage III, and 15 with Stage IV. Six Stage I tumors had surgery, as did 20 Stage II, 12 Stage III, and 13 Stage IV. Chemotherapy was given to 1 Stage II tumor, 7 Stage III, and 5 Stage IV. No patient with Stages I or II disease died. Four Stage III patients (15 percent) and 8 Stage IV patients (44 percent) died from desmoids. Finally 89 percent with Stage I, 65 percent with Stage II, 59 percent with Stage III, and 50 percent with Stage IV disease were asymptomatic; 81 percent of Stage I desmoids, 78 percent of Stage II, 42 percent of Stage III, and 28 percent of Stage IV were stable or disappeared. CONCLUSION: Desmoid staging identifies tumors by prognosis and its use for designing prospective treatment studies is reasonable.

The peritoneum is the second most common site of metastasis after the liver and the only site of metastatic disease in approximately 25% of patients with colorectal cancer (CRC). In the past, peritoneal carcinomatosis in CRC was thought to be equivalent to distant metastasis; however, the transcoelomic spread of malignant cells is an acknowledged alternative pathway. Metastasectomy with curative intent is well accepted in patients with liver metastasis in CRC despite the paucity of randomized trials. Therefore, there is rationale for local treatment with peritonectomy to eliminate macroscopic disease, followed by hyperthermic intraperitoneal chemotherapy to destroy any residual free tumour cells within the peritoneal cavity. The aim of this paper is to summarize the current evidence for cytoreduction and hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal carcinomatosis in CRC.

PURPOSE/OBJECTIVES: To ascertain individual experiences of extended bowel resection as treatment for colorectal cancer (CRC) in those with a high metachronous CRC risk, including the self-reported adequacy of information received at different time points of treatment and recovery.â©. RESEARCH APPROACH: Qualitative.â©. SETTING: Participants were recruited through the Australasian Colorectal Cancer Family Registry and two hospitals in Melbourne, Australia.â©. PARTICIPANTS: 18 individuals with a high metachronous CRC risk who had an extended bowel resection from 6-12 months ago.â©. METHODOLOGIC APPROACH: Semistructured interviews. Data were analyzed thematically.â©. FINDINGS: In most cases, the treating surgeon decided on the best option regarding surgical treatment. Participants felt well informed about the surgical procedure. Information related to surgical outcomes, recovery, and lifestyle adjustment from surgery was not always adequate. Many participants described ongoing worry about developing another cancer. â©. CONCLUSIONS: Patients undergoing an extended resection to reduce metachronous CRC risk require detailed information delivered at more than one time point and relating to several different aspects of the surgical procedure and its outcomes.â©. INTERPRETATION: An increased emphasis should be given to the provision of patient information on surgical outcomes, recovery, and lifestyle adjustment. Colorectal nurses could provide support for some of the reported unmet needs.

PURPOSE: To evaluate the prognostic factors, patterns of failure, and late toxicity in patients treated with chemoradiation (CRT) for anal cancer. METHODS AND MATERIALS: Consecutive patients with nonmetastatic squamous cell carcinoma of the anus treated by CRT with curative intent between February 1983 and March 2008 were identified through the institutional database. Chart review and telephone follow-up were undertaken to collect demographic data and outcome. RESULTS: Two hundred eighty-four patients (34% male; median age 62 years) were identified. The stages at diagnosis were 23% Stage I, 48% Stage II, 10% Stage IIIA, and 18% Stage IIIB. The median radiotherapy dose to the primary site was 54 Gy. A complete clinical response to CRT was achieved in 89% of patients. With a median follow-up time of 5.3 years, the 5-year rates of locoregional control, distant control, colostomy-free survival, and overall survival were 83% (95% confidence interval [CI] 78-88), 92% (95% CI, 89-96), 73% (95% CI, 68-79), and 82% (95% CI, 77-87), respectively. Higher T stage and male sex predicted for locoregional failure, and higher N stage predicted for distant metastases. Locoregional failure occurred most commonly at the primary site. Omission of elective inguinal irradiation resulted in inguinal failure rates of 1.9% and 12.5% in T1N0 and T2N0 patients, respectively. Pelvic nodal failures were very uncommon. Late vaginal and bone toxicity was observed in addition to gastrointestinal toxicity. CONCLUSIONS: CRT is a highly effective approach in anal cancer. However, subgroups of patients fare relatively poorly, and novel approaches are needed. Elective inguinal irradiation can be safely omitted only in patients with Stage I disease. Vaginal toxicity and insufficiency fractures of the hip and pelvis are important late effects that require prospective evaluation.

INTRODUCTION: Desmoid tumors are a clinical problem in 12 to 15 percent of patients with familial adenomatous polyposis. There is no predictably effective treatment for intra-abdominal desmoid tumors, which sometimes cause significant complications by their effects on the ureters or bowel. The relative rarity and the clinical heterogeneity of intra-abdominal desmoid tumors make randomized studies difficult to do. In this article a staging system is proposed to make multi-institutional studies easier. METHODS: Intra-abdominal desmoid tumors can be staged according to their size, clinical presentation and growth pattern. CONCLUSION: A way of staging intra-abdominal desmoid tumors is proposed to facilitate stratification by disease severity during collaborative studies of various treatments.
