RESUMEN

BACKGROUND: Tumor-infiltrating lymphocyte (TIL) therapy has been restricted by intensive lymphodepletion and high-dose intravenous interleukin-2 (IL-2) administration. To address these limitations, we conducted preclinical and clinical studies to evaluate the safety, antitumor activity, and pharmacokinetics of an innovative modified regimen in patients with advanced gynecologic cancer. METHODS: Patient-derived xenografts (PDX) were established from a local recurrent cervical cancer patient. TILs were expanded ex vivo from minced tumors without feeder cells in the modified TIL therapy regimen. Patients underwent low-dose cyclophosphamide lymphodepletion followed by TIL infusion without intravenous IL-2. The primary endpoint was safety; the secondary endpoints included objective response rate, duration of response, and T cell persistence. RESULTS: In matched patient-derived xenografts (PDX) models, homologous TILs efficiently reduced tumor size (p < 0.0001) and underwent IL-2 absence in vivo. In the clinical section, all enrolled patients received TIL infusion using a modified TIL therapy regimen successfully with a manageable safety profile. Five (36%, 95% CI 16.3-61.2) out of 14 evaluable patients experienced objective responses, and three complete responses were ongoing at 19.5, 15.4, and 5.2 months, respectively. Responders had longer overall survival (OS) than non-responders (p = 0.036). Infused TILs showed continuous proliferation and long-term persistence in all patients and showed greater proliferation in responders which was indicated by the Morisita overlap index (MOI) of TCR clonotypes between infused TILs and peripheral T cells on day 14 (p = 0.004) and day 30 (p = 0.004). Higher alteration of the CD8+/CD4+ ratio on day 14 indicated a longer OS (p = 0.010). CONCLUSIONS: Our modified TIL therapy regimen demonstrated manageable safety, and TILs could survive and proliferate without IL-2 intravenous administration, showing potent efficacy in patients with advanced gynecologic cancer. TRIAL REGISTRATION: NCT04766320, Jan 04, 2021.

RESUMEN

PURPOSE: The purpose of this study was to gain an understanding of older gynecologic cancer patients' preferences and opinions related to physical activity during chemotherapy, including interventions to promote physical activity. METHODS: Gynecologic cancer patients 60 years or older receiving chemotherapy at a single institution within the last 12 months completed questionnaires and a semi-structured interview asking about their preferences for physical activity interventions aimed at promoting physical activity while receiving treatment. RESULTS: Among the 30 gynecologic cancer patients surveyed and interviewed, a majority agreed with the potential usefulness of a physical activity intervention during chemotherapy (67%) and most reported they would be willing to use an activity tracker during chemotherapy (73%). They expressed a preference for an aerobic activity intervention such as walking, indicated a desire for education from their clinical team on the effects physical activity can have on treatment symptoms, and stated a need for an intervention that could be accessed from anywhere and anytime. Additionally, they emphasized a need for an intervention that considered their treatment symptoms as these were a significant barrier to physical activity while on chemotherapy. CONCLUSION: In this study of older gynecologic cancer patients receiving chemotherapy, most were open to participating in a virtually accessible and symptom-tailored physical activity intervention to promote physical activity during chemotherapy.

RESUMEN

Programmed death-1 (PD-1) inhibitors are approved for therapy of gynecologic cancers with DNA mismatch repair deficiency (dMMR), although predictors of response remain elusive. We conducted a single-arm phase 2 study of nivolumab in 35 patients with dMMR uterine or ovarian cancers. Co-primary endpoints included objective response rate (ORR) and progression-free survival at 24 weeks (PFS24). Secondary endpoints included overall survival (OS), disease control rate (DCR), duration of response (DOR) and safety. Exploratory endpoints included biomarkers and molecular correlates of response. The ORR was 58.8% (97.5% confidence interval (CI): 40.7-100%), and the PFS24 rate was 64.7% (97.5% one-sided CI: 46.5-100%), meeting the pre-specified endpoints. The DCR was 73.5% (95% CI: 55.6-87.1%). At the median follow-up of 42.1 months (range, 8.9-59.8 months), median OS was not reached. One-year OS rate was 79% (95% CI: 60.9-89.4%). Thirty-two patients (91%) had a treatment-related adverse event (TRAE), including arthralgia (n = 10, 29%), fatigue (n = 10, 29%), pain (n = 10, 29%) and pruritis (n = 10, 29%); most were grade 1 or grade 2. Ten patients (29%) reported a grade 3 or grade 4 TRAE; no grade 5 events occurred. Exploratory analyses show that the presence of dysfunctional (CD8+PD-1+) or terminally dysfunctional (CD8+PD-1+TOX+) T cells and their interaction with programmed death ligand-1 (PD-L1)+ cells were independently associated with PFS24. PFS24 was associated with presence of MEGF8 or SETD1B somatic mutations. This trial met its co-primary endpoints (ORR and PFS24) early, and our findings highlight several genetic and tumor microenvironment parameters associated with response to PD-1 blockade in dMMR cancers, generating rationale for their validation in larger cohorts.ClinicalTrials.gov identifier: NCT03241745 .

RESUMEN

PURPOSE: Markman's desensitisation protocol allows successful retreatment of patients who have had significant paclitaxel hypersensitivity reactions. We aimed to reduce the risk and severity of paclitaxel hypersensitivity reactions by introducing this protocol as primary prophylaxis. METHODS: We evaluated all patients with a gynaecological malignancy receiving paclitaxel before (December 2018 to September 2019) and after (October 2019 to July 2020) the implementation of a modified Markman's desensitisation protocol. The pre-implementation group received paclitaxel over a gradually up-titrated rate from 60 to 180 ml/h. The post-implementation group received paclitaxel via 3 fixed-dose infusion bags in the first 2 cycles. Rates and severity of paclitaxel hypersensitivity reactions were compared. RESULTS: A total of 426 paclitaxel infusions were administered to 78 patients. The median age was 64 years (range 34-81), and the most common diagnosis was ovarian, fallopian tube and primary peritoneal cancer (67%, n = 52/78). Paclitaxel hypersensitivity reaction rates were similar in the pre-implementation (8%, n = 16/195) and post-implementation groups (9%, n = 20/231; p = 0.87). Most paclitaxel hypersensitivity reactions occurred within 30 min (pre- vs. post-implementation, 88% [n = 14/16] vs. 75% [n = 15/20]; p = 0.45) and were grade 2 in severity (pre- vs. post-implementation, 81% [n = 13/16] vs. 75% [n = 15/20]; p = 0.37). There was one grade 3 paclitaxel hypersensitivity reaction in the pre-implementation group. All patients were successfully rechallenged in the post-implementation group compared to 81% (n = 13/16) in the pre-implementation group (p = 0.43). CONCLUSION: The modified Markman's desensitisation protocol as primary prophylaxis did not reduce the rate or severity of paclitaxel hypersensitivity reactions, although all patients could be successfully rechallenged.

RESUMEN

Enoxaparin and daikenchuto are commonly administered to prevent venous thromboembolism and intestinal obstruction after gynecological malignancy surgery. However, the effects of their combined use on hepatic function are not well studied. This study aimed to clarify the effects of the coadministration of enoxaparin and daikenchuto on hepatic function. First, Japanese Adverse Drug Event Report (JADER) data were analyzed to identify signals of hepatic disorders. Second, a retrospective observational study of patients who underwent surgery for gynecological malignancies was conducted. This study defined hepatic disorders as an increase in aspartate aminotransferase (AST) or alanine aminotransaminase (ALT) levels above the reference values, using 1-h postoperative values as the baseline. The analysis of JADER data revealed an increased risk for hepatic disorders with the coadministration of enoxaparin and daikenchuto. An observational study also showed higher odds ratios (95% confidence intervals) for the occurrence of hepatic disorders in the coadministration group (4.27; 2.11-8.64) and enoxaparin alone group (2.48; 1.31-4.69) than in the daikenchuto alone group. The median increase in the ALT level was also higher in the coadministration group (34; 15-59) than in the enoxaparin alone (19; 6-38) and daikenchuto alone groups (8; 3-33). In conclusion, our study suggests that compared with the use of enoxaparin or daikenchuto alone, enoxaparin and daikenchuto coadministration increases the risk of hepatic disorders, with more significant increases in AST and ALT levels. Healthcare workers need to be aware of these potential side effects when combining these drugs after surgery for gynecological malignancies.

RESUMEN

The purpose of this study is to establish the recommended phase 2 dose for regorafenib in combination with sildenafil for patients with advanced solid tumors. Secondary outcomes included identification of antitumor effects of regorafenib and sildenafil, toxicity of the combination, determination of PDE5 expression in tumor samples, and the impact of sildenafil on the pharmacokinetics of regorafenib. This study was a phase 1, open-label single-arm dose-escalation trial using a 3 + 3 design. Additional patients were enrolled at the maximum tolerated dose (MTD) until a total of 12 patients were treated at the MTD. A total of 29 patients were treated in this study. The median duration of treatment was 8 weeks. The recommended phase 2 doses determined in this study are regorafenib 160 mg daily with sildenafil 100 mg daily. The most common toxicities included palmar-plantar erythrodysesthesia syndrome (20 patients, 69%) and hypophosphatemia (18 patients, 62%). Two patients (7%) experienced grade 4 lipase increase. Objective responses were not observed; however, 14 patients (48%) had a period of stable disease during the study. Stable disease for up to 12 months was observed in patients with ovarian cancer as well as up to 20 months for a patient with cervical cancer. The combination of regorafenib and sildenafil at the recommended phase 2 dose is safe and generally well tolerated. Disease control in patients with gynecologic malignancies was especially encouraging. Further evaluation of the combination of regorafenib and sildenafil in gynecologic malignancies is warranted. Clinical Trial Registration Number: NCT02466802.

RESUMEN

ABSTRACT: Concurrent cervical cancer with advanced pelvic organ prolapse is rare: there are no well-established treatment recommendations. It is hypothesized that chronic irritation, as with long-standing pelvic organ prolapse, may lead to dysplasia and human papillomavirus-independent carcinoma, which represents only 5% of cervical cancers. Two patients with complete uterine procidentia were referred to gynecologic oncology with cervical squamous cell carcinoma; both were clinically staged as International Federation of Gynaecology and Obstetrics IB3. Treatment planning was complicated by procidentia in both cases. Standard definitive treatment of locally advanced cervical cancer is radiation therapy and concurrent chemotherapy; however, the mobility and externalization of the target lesion raised concerns regarding anatomic reproducibility during radiation treatment. After multidisciplinary team discussion (gynecologic oncology, urogynecology, radiation oncology), surgical resection and co-management with gynecologic oncology and urogynecology were successfully performed for definitive management for both patients. Although rare, this case study demonstrates the importance of multidisciplinary coordination in these complex clinical scenarios.

RESUMEN

In the 2023 series, we summarized the major clinical research advances in gynecologic oncology based on communications at the conference of Asian Society of Gynecologic Oncology Review Course. The review consisted of 1) Endometrial cancer: immune checkpoint inhibitor, antibody drug conjugates (ADCs), selective inhibitor of nuclear export, CDK4/6 inhibitors WEE1 inhibitor, poly (ADP-ribose) polymerase (PARP) inhibitors. 2) Cervical cancer: surgery in low-risk early-stage cervical cancer, therapy for locally advanced stage and advanced, metastatic, or recurrent setting; and 3) Ovarian cancer: immunotherapy, triplet therapies using immune checkpoint inhibitors along with antiangiogenic agents and PARP inhibitors, and ADCs. In 2023, the field of endometrial cancer treatment witnessed a landmark year, marked by several practice-changing outcomes with immune checkpoint inhibitors and the reliable efficacy of PARP inhibitors and ADCs.

RESUMEN

Ovarian cancer is a significant challenge in women's health due to the lack of effective screening and diagnostic methods, often leading to late detection and the highest mortality rate among all gynecologic tumors worldwide. Recent research has shown that ovarian cancer has an "iron addiction" phenotype which makes it vulnerable to ferroptosis inducers. We tested the combination of NRF2-targeted inhibitors with GPX4-targeted inhibitors in ovarian cancer through in vitro and in vivo experiment. The data showed that combination treatment effectively suppressed adherent cell growth, inhibited suspended cell spheroid formation, and restrained the ability of spheroid formation in 3D-culture. Mechanistically, the combination induced accumulation of ROS, 4-HNE, as well as activation of caspase-3 which indicates that this combination simultaneously increases cell ferroptosis and apoptosis. Notably, inhibition of GPX4 or NRF2 can suppress ovarian cancer spreading and growth in the peritoneal cavity of mice, while the combination of NRF2 inhibitor ML385 with GPX4 inhibitors showed a significant synergistic effect compared to individual drug treatment in a syngeneic mouse ovarian cancer model. Overall, these findings suggest that combining NRF2 inhibitors with GPX4 inhibitors results in a synergy suppression of ovarian cancer in vitro and in vivo, and maybe a promising therapeutic strategy for the treatment of ovarian cancer.

RESUMEN

Advances in molecular tumor diagnostics have transformed cancer care. However, it remains unclear whether precision oncology has the same impact and transformative nature across all malignancies. We conducted a retrospective analysis of patients with human papillomavirus (HPV)-related gynecologic malignancies who underwent comprehensive molecular profiling and subsequent discussion at the interdisciplinary Molecular Tumor Board (MTB) of the University Hospital, LMU Munich, between 11/2017 and 06/2022. We identified a total cohort of 31 patients diagnosed with cervical (CC), vaginal or vulvar cancer. Twenty-two patients (fraction: 0.71) harbored at least one mutation. Fifteen patients (0.48) had an actionable mutation and fourteen (0.45) received a recommendation for a targeted treatment within the MTB. One CC patient received a biomarker-guided treatment recommended by the MTB and achieved stable disease on the mTOR inhibitor temsirolimus for eight months. Factors leading to non-adherence to MTB recommendations in other patient cases included informed patient refusal, rapid deterioration, stable disease, or use of alternative targeted but biomarker-agnostic treatments such as antibody-drug conjugates or checkpoint inhibitors. Despite a remarkable rate of actionable mutations in HPV-related gynecologic malignancies at our institution, immediate implementation of biomarker-guided targeted treatment recommendations remained low, and access to targeted treatment options after MTB discussion remained a major challenge.

RESUMEN

OPINION STATEMENT: Antibody-drug conjugates (ADCs) are a novel class of targeted cancer therapies with the ability to selectively deliver a cytotoxic drug to a tumor cell using a monoclonal antibody linked to a cytotoxic payload. The technology of ADCs allows for tumor-specificity, improved efficacy, and decreased toxicity compared to standard chemotherapy. Common toxicities associated with ADC use include ocular, pulmonary, hematologic, and neurologic toxicities. Several ADCs have been approved by the United States Food and Drug Administration (FDA) for the management of patients with recurrent or metastatic gynecologic cancers, a population with poor outcomes and limited effective treatment options. The first FDA-approved ADC for recurrent or metastatic cervical cancer was tisotumab vedotin, a tissue factor-targeting agent, after demonstrating response in the innovaTV 204 trial. Mirvetuximab soravtansine targets folate receptor alpha and is approved for use in patients with folate receptor alpha-positive, platinum-resistant, epithelial ovarian cancer based on results from the SORAYA trial. While there are no FDA-approved ADCs for the treatment of uterine cancer, trastuzumab deruxtecan, an anti-human epidermal growth factor receptor 2 (HER2) agent, is actively being investigated. In this review, we will describe the structure and mechanism of action of ADCs, discuss their toxicity profiles, review ADCs both approved and under investigation for the management of gynecologic cancers, and discuss mechanisms of ADC resistance.

RESUMEN

Gynecological cancers are serious life-threatening diseases responsible for high morbidity and mortality around the world. Chemotherapy, radiotherapy, and surgery are considered standard therapeutic modalities for these cancers. Since the mentioned treatments have undesirable side effects and are not effective enough, further attempts are required to explore potent complementary and/or alternative treatments. This study was designed to review and discuss the anticancer potentials of baicalin against gynecological cancers based on causal mechanisms and underlying pathways. Traditional medicine has been used for thousands of years in the therapy of diverse human diseases. The therapeutic effects of natural compounds like baicalin have been widely investigated in cancer therapy. Baicalin was effective against gynecological cancers by regulating key cellular mechanisms, including apoptosis, autophagy, and angiogenesis. Baicalin exerted its anticancer property by regulating most molecular signaling pathways, including PI3K/Akt/mTOR, NFκB, MAPK/ERK, and Wnt/ß-catenin. However, more numerous experimental and clinical studies should be designed to find the efficacy of baicalin and the related mechanisms of action.

RESUMEN

PURPOSE: The market and application possibilities for artificial intelligence are currently growing at high speed and are increasingly finding their way into gynecology. While the medical side is highly represented in the current literature, the patient's perspective is still lagging behind. Therefore, the aim of this study was to evaluate the recommendations of ChatGPT regarding patient inquiries about the possible therapy of gynecological leading symptoms in a palliative situation by experts. METHODS: Case vignettes were constructed for 10 common concomitant symptoms in gynecologic oncology tumors in a palliative setting, and patient queries regarding therapy of these symptoms were generated as prompts for ChatGPT. Five experts in palliative care and gynecologic oncology evaluated the responses with respect to guideline adherence and applicability and identified advantages and disadvantages. RESULTS: The overall rating of ChatGPT responses averaged 4.1 (5 = strongly agree; 1 = strongly disagree). The experts saw an average guideline conformity of the therapy recommendations with a value of 4.0. ChatGPT sometimes omits relevant therapies and does not provide an individual assessment of the suggested therapies, but does indicate that a physician consultation is additionally necessary. CONCLUSIONS: Language models, such as ChatGPT, can provide valid and largely guideline-compliant therapy recommendations in their freely available and thus in principle accessible version for our patients. For a complete therapy recommendation, an evaluation of the therapies, their individual adjustment as well as a filtering of possible wrong recommendations, a medical expert's opinion remains indispensable.

RESUMEN

BACKGROUND: Current international guidelines recommend 28 days of enoxaparin as venous thromboembolism (VTE) prophylaxis after surgery for gynaecologic cancer. Direct oral anticoagulants (DOACs) have been investigated as an alternative to enoxaparin for post-operative VTE prophylaxis. High-quality evidence to demonstrate safety and efficacy is lacking. AIMS: We aim to investigate the current practice regarding VTE prophylaxis among gynaecological oncologists in Australia and New Zealand following laparotomy for gynaecological malignancy, in particular the use of DOACs for VTE prophylaxis. MATERIALS AND METHODS: Sixty-seven practising gynaecologic oncologists (GO) were identified through Royal Australia and New Zealand College of Obstetricians and Gynaecologists database and emailed online surveys that asked about VTE prophylaxis practice and views of DOACs in this setting. Data were then collected through Survey Monkey and evaluated. RESULTS: The majority (77.1%) routinely prescribed 28 days of enoxaparin following laparotomy for gynaecological malignancies. In clinical circumstance such as laparoscopy for gynaecological malignancies and surgery for vulva malignancies, there was variation in thromboprophylaxis practices. No GO reported routine use of DOACs in any clinical circumstance. There were 56% of GOs who used a DOAC in their practice at some point. Barriers to routine use of DOACs in current practice included insufficient evidence (68%), issue with cost (40.4%) and concerns about safety (29.7%). CONCLUSIONS: Enoxaparin prescribed for 28 days remains the current clinical practice in preventing VTE following laparotomy for gynaecological malignancy. The main barrier to routine DOAC use as post-operative thromboprophylaxis is a lack of evidence which reflects the need for a larger prospective study.

RESUMEN

OBJECTIVE: Gynecologic cancer chemotherapy impacts the quality of life (QOL) of patients, with lasting adverse events that may require treatment adjustments or discontinuation. Consequently, real-time symptom monitoring before outpatient visits has resulted in improved QOL for patients and extended survival times. This study investigated whether there are differences between electronic patient-reported outcomes (e-PRO-CTCAE) and physician-assessed outcomes (NCI-CTCAE) evaluated in an outpatient setting in gynecologic cancer chemotherapy. METHODS: The study was conducted on 50 patients who received their first chemotherapy treatment at St. Marianna University Hospital Obstetrics and Gynecology from July 1, 2021 to December 31, 2022. PRO-CTCAE and NCI-CTCAE were evaluated at each instance of chemotherapy and 2 weeks after. The PRO-CTCAE was additionally collected weekly using e-PRO. RESULTS: The values for "Joint Pain," "Nausea," "Taste Disturbance," "Constipation," "Insomnia," "Fatigue," "Limb Edema," and "Concentration Impairment" were consistently higher in PRO-CTCAE than in NCI-CTCAE, indicating that physicians underestimated the severity of adverse events. In contrast, there was no significant difference in "Peripheral Neuropathy," demonstrating that physicians had a good understanding of this condition in patients. The weekly responses obtained from e-PRO revealed that symptom exacerbations peaked outside of clinic visits. CONCLUSIONS: This study demonstrated physicians tend to underestimate most adverse events. Moreover, the responses using e-PRO revealed peak symptom deterioration occurred outside of outpatient visits. This suggested that e-PRO and actions taken in response to them can improve patients' QOL.

RESUMEN

OBJECTIVE: The approved standard dose of pembrolizumab (200 mg administrated every 3 weeks) for cancer treatment imposes a significant financial burden on patients. However, no study has analyzed the clinical outcomes of low-dose pembrolizumab among individuals diagnosed with gynecologic cancer. The primary objective of this study was to assess the effectiveness and safety of a low-dose pembrolizumab regimen in real-world clinical practice. METHODS: We retrospectively assessed the efficacy and safety data of patients with gynecologic malignancies who received pembrolizumab between 2017 and 2022 at Kaohsiung Chang Gung Memorial Hospital. Furthermore, we conducted a comparative analysis of the objective response rate (ORR) and progression-free survival (PFS) between patients with deficient mismatch repair (dMMR) and proficient MMR (pMMR). RESULTS: A total of thirty-nine patients were included and received pembrolizumab at fixed dosages of 50 mg (5.1%), 100 mg (84.6%) and 200 mg (10.3%) per cycle. Compared to the pMMR group, the dMMR group exhibited a tendency toward improved ORR (45.5% vs. 13.0%, p = 0.074), and notably, the median duration of response remained unreached. There was no significant difference in PFS between the dMMR and pMMR groups; however, the patients with dMMR in tumor tissue had a trend of better survival (p = 0.079). Incidence of immune-related adverse events (irAEs) of any grade was observed in 13 patients (33.3%), with 3 individuals (7.7%) experiencing grade 3 or 4 events. CONCLUSION: Low-dose pembrolizumab may be a cost-effective and safe treatment option without compromising clinical outcomes in patients with refractory gynecologic cancers.

RESUMEN

BACKGROUND: Immune checkpoint blockade has shown mixed results in advanced/recurrent gynecologic malignancies. Efficacy may be improved through costimulation with OX40 and 4-1BB agonists. The authors sought to evaluate the safety and efficacy of avelumab combined with utomilumab (a 4-1BB agonist), PF-04518600 (an OX40 agonist), and radiotherapy in patients with recurrent gynecologic malignancies. METHODS: The primary end point in this six-arm, phase 1/2 trial was safety of the combination regimens. Secondary end points included the objective response rate (ORR) according to Response Evaluation Criteria in Solid Tumors and immune-related Response Evaluation Criteria in Solid Tumors, the disease control rate (DCR), the duration of response, progression-free survival, and overall survival. RESULTS: Forty patients were included (35% with cervical cancer, 30% with endometrial cancer, and 35% with ovarian cancer). Most patients (n = 33; 83%) were enrolled in arms A-C (no radiation). Among 35 patients who were evaluable for efficacy, the ORR was 2.9%, and the DCR was 37.1%, with a median duration of stable disease of 5.4 months (interquartile range, 4.1-7.3 months). Patients with cervical cancer in arm A (avelumab and utomilumab; n = 9 evaluable patients) achieved an ORR of 11% and a DCR of 78%. The median progression-free survival was 2.1 months (95% CI, 1.8-3.5 months), and overall survival was 9.4 months (95% CI, 5.6-11.9 months). No dose-limiting toxicities or grade 3-5 immune-related adverse events were observed. CONCLUSIONS: The findings from this trial highlight that, in heavily pretreated patients with gynecologic cancer, even multidrug regimens targeting multiple immunologic pathways, although safe, did not produce significant responses. A DCR of 78% in patients with cervical cancer who received avelumab and utomilumab indicates that further research on this combination in select patients may be warranted.

RESUMEN

BACKGROUND: Patients with cancer experience symptoms concurrently. Nurses need to make multisymptom management and educate patients about self-management strategies. OBJECTIVE: The aim of this study was to evaluate the effect of a nurse-led symptom management program (NL-SMP), developed based on the Symptom Management Model, quality of life (QoL), and symptom severity of women with gynecological cancer undergoing chemotherapy. METHODS: This randomized controlled study sample consisted of 41 women receiving chemotherapy at an outpatient clinic in Istanbul, Turkey, between November 2018 and December 2019. European Organisation for Research and Treatment of Cancer Quality-of-Life Scale, Edmonton Symptom Assessment Scale, and Modified Brief Sexual Symptom Checklist-Women were used to collect data. Women were randomly assigned to 2 groups: intervention (n = 21) and control (n = 20). The intervention group attended the NL-SMP in addition to usual care. Data were collected at the first (time 1), third (time 2), and last chemotherapy cycle (time 3). Repeated measures analysis of variance, Cochran-Q, and t tests were used to analyze the data. RESULTS: In the intervention group, the QoL was significantly higher; symptom severity was lower than that of the control group at time 2 and time 3. At time 3, more women in the control group reported at least 1 sexual difficulty and were not satisfied with their sexual function, whereas there was no change for women in the intervention group. CONCLUSION: The NL-SMP, which consisted of systematic symptom assessment, prioritization of symptoms, providing symptom, and patient-specific education, decreased deterioration in the QoL and symptom severity of women. IMPLICATIONS FOR PRACTICE: Conducting multisymptom assessments, prioritizing symptoms, providing symptom- and patient-specific education, and supporting symptom self-management throughout treatment can lead to effective symptom management.

RESUMEN

Introduction: energy metabolism in cancer patients is influenced by different factors. However, the effect of antineoplastic treatment is not clear, especially in women. Objective: to evaluate resting energy expenditure (REE) by indirect calorimetry (IC) before (T0) and after (T1) first cycle period of antineoplastic therapy: radiotherapy (RT), chemotherapy (CT), and concomitant chemoradiation therapy (CRT), quality of life (QoL) and accuracy of REE were compared with international guidelines recommendations per kilogram (European Society for Clinical Nutrition and Metabolism [ESPEN]). Methods: an observational, longitudinal study was conducted in women with gynecological cancer diagnosis undergoing antineoplastic treatment: RT, CT and CRT. Weight loss, actual body weight and height were measured. REE was evaluated in T0-T1 and compared with ESPEN recommendations. Kruskal-Wallis test and Bland-Alman analysis were used to determine the agreement (± 10 % of energy predicted) of REE adjusted by physical activity (TEE) compared with ESPEN recommendations, respectively. Results: fifty-four women with cancer were included: 31.5 % (n = 17) for RT group, 31.5 % (n = 17) for CT group and 37 % (n = 20) for CRT group. REE showed statistical differences between T0 and T1 in the total population (p = 0.018), but these were not associated with anticancer therapy groups (p > 0.05). QoL had no significant changes after treatment (p > 0.05). Accuracy of 25 and 30 kcal/kg compared to TEE was less than 30 %. Conclusion: REE in women with gynecological cancer decreased after antineoplastic treatments but this is not associated with a particular antineoplastic therapy. It is needed to develop research to determine the accuracy of ESPEN recommendations with TEE estimated by IC and clinical factors in women with cancer. (AU)


Antecedentes: el metabolismo energético en pacientes con cáncer está influenciado por diferentes factores. Sin embargo, el efecto sobre el tratamiento antineoplásico no es claro, especialmente en mujeres. Objetivo: evaluar el gasto energético en reposo (GER) mediante calorimetría indirecta (CI) antes (T0) y después (T1) del primer ciclo del tratamiento antineoplásico: radioterapia (RT), quimioterapia (QT) y quimio-radioterapia concomitante (QRT), calidad de vida (CdV) y precisión del GER con las con las recomendaciones internacionales por kilogramo de peso (European Society for Clinical Nutrition and Metabolism [ESPEN]). Métodos: se realizó un estudio longitudinal, observacional en mujeres con diagnóstico de cáncer ginecológico en tratamiento antineoplásico. Se evaluó el GER en T0 y T1. Se midieron la pérdida de peso, el peso corporal y la talla. Se usaron las pruebas de Kruskal-Wallis y el análisis Bland-Altman para determinar la concordancia (± 10 % de GER) del REE ajustado por actividad física (TEE) en comparación con las recomendaciones de ESPEN. Resultados: se incluyeron 54 mujeres con cáncer; 31,5 % (n = 17) en el grupo RT, 31,5 % (n = 17) en el de QT y 37 % (n = 20) en el de QRT. GER mostró diferencias estadísticas entre T0 y T1 en la población total (p = 0,018); no se asoció con la terapia contra el cáncer (p > 0,05). La calidad de vida no tuvo cambios significativos después del tratamiento (p > 0,05). La precisión de 25 y 30 kcal/kg en comparación con TEE fue inferior al 30 %. Conclusión: el GER en mujeres con cáncer ginecológico disminuyó después del tratamiento antineoplásico, pero no se asoció a una terapia antineoplásica en particular. Es fundamental desarrollar más investigaciones que compare las recomendaciones de ESPEN y con los valores de la CI comparando más factores clínicos para ofrecer una intervención nutricional precisa (AU)

RESUMEN

OBJECTIVES: To explore the use of complementary and alternative medicine (CAM) by Chinese gynaecological oncology patients undergoing chemotherapy and discuss measures to address the existing gaps. DESIGN: Qualitative phenomenology. Semistructured in-depth interview. Colaizzi's method data analysis. SETTING: A tertiary general hospital. PARTICIPANTS: 16 gynaecological oncology patients (mean age 51.7) having undergone ≥1 chemotherapy cycle were recruited by purposive sampling. RESULTS: Six themes were generated. The participants were under-informed about CAM concept and options. They were open to explore various modalities after chemotherapy as long as it could alleviate symptoms. The gynaecological patients with cancer sought information about CAM from diverse sources, with professional expertise being the most desirable way to seek information. They used CAM as a strategy to support continued chemotherapy and for symptom alleviation. Financial burden was not stressed but they had concerns about sustainability of some therapies. Their attitudes toward different CAM types varied. Some were sceptical about the efficacy. CONCLUSIONS: The Chinese gynaecological oncology patients may be under-informed about CAM. They are open to use various CAM therapies for symptom relief and as a support strategy. However, their attitudes toward specific therapies may vary. Some may host scepticism about certain CAM modalities. The patients actively seek information on CAM and treatment resources but prefer professional expertise to other sources. Financial burden due to continued CAM use is inconclusive due to possible sampling bias. Sustainability of CAM therapies is a common concern because of limited resources and access. Education on CAM should be incorporated into the curriculum of healthcare professionals. Oncologists and nurses should educate gynaecological patients with cancer on the concept and options of CAM, preferably with information tailored to patient's individual needs. Health authorities should advocate provisions of diverse CAM services and develop the necessary technologies such as network of local care resources.
