Ovarian stimulation response and fertility outcomes in patients with breast cancer across different stages, grades, and hormone receptor status for fertility preservation.

BACKGROUND: This study aimed to explore the potential impact of stage, grade, and hormone receptor profile on ovarian stimulation response and fertility preservation outcomes. METHODS: This retrospective cohort study evaluated data from breast cancer patients who underwent fertility preservation at a tertiary medical center between 2014 and 2022. The outcomes of women with low-stage cancer (stages I and II) were compared with those of women with high-stage disease (stages III and IV or lymph node metastasis). Similarly, we compared those with low-grade (grades 1 and 2) and high-grade (grade 3) malignancies. In addition, we compared different hormone statuses of breast cancer (1) estrogen receptor (ER) positive vs. ER-negative and (2) triple-negative breast cancer (TNBC) vs. non-TNBC. The primary outcome measured was the number of mature oocytes, while the secondary outcomes included the numbers of total oocytes retrieved, peak estradiol levels, and subsequent fertility preservation outcomes. RESULTS: A total of 47 patients were included. Patients with high-grade tumors had a comparable number of mature oocytes (8 vs. 10, p = 0.08) compared to patients with low grade cancers. The stage-based analysis revealed a similar number of mature oocytes (8 vs. 10, p = 0.33) between high/low stage patients. In the hormone receptor-based analysis, no differences were seen in mature oocytes collected between the ER-positive/ER-negative group (9 vs. 9, p = 0.87) and the TNBC/non-TNBC group (11 vs. 9, p = 0.13). The utilization rate was 27.6% (13/47). CONCLUSION: Our study showed similar ovarian stimulation response and fertility preservation outcomes among breast cancer patients with different prognostic factors.

Application of parametric survival analysis to women patients with breast cancer at Jimma University Medical Center.

Public health systems in both industrialized and undeveloped countries continue to struggle with the worldwide problem of breast cancer. In sub-Saharan African countries, notably Ethiopia, it is the form of cancer that strikes women the most commonly. Despite the extreme difficulties, the causes of mortality in Ethiopia have not yet been identified. In addition, little study has been done in this area. Therefore, the major objective of this analysis was to pinpoint the factors that were most responsible for the decreased life expectancy of breast cancer patients at the University of Jimma Medical Center. 552 women who had been treated for breast cancer at Jimma University Medical Center between October 2018 and December 2022 were included in this study, which used a retrospective cohort study design and five-year follow-up data. The most frequent and widely used test for comparing the probability of survival curves between several categorical independent variables was the log-rank test. Next, semi-parametric methods for multivariable analysis using the Cox proportional hazards model were used. Furthermore, a parametric strategy that includes fully parametric survival models better achieves the goal of the analysis. Among covariate, age of patient (ϕ = 254.06; 95% CI (3.95, 7.13), P-value = 0.000), patient live in urban (ϕ = 0.84; 95% CI (-0.35,-0.00), P-value = 0.047), preexisting comorbidity (ϕ = 2.46; 95% CI (0.39, 1.41), P-value = 0.001), overweight women cancer patient (ϕ = 0.05; 95% CI(-4.41,-1.57), P-value = 0.000, positive Axillary Node status cancer patient (ϕ = 0.04; 95% CI(-4.45,-1.88), P-value = 0.000), both surgery and chemotropic baseline treatment patient (ϕ = 0.53; 95% CI(-1.12,-0.16), P-value = 0.009) significantly affected the survival of women breast cancer. Age of breast cancer patient, patient education level, place of residence, marital status, pre-existing comorbidity, axillary node status, estrogen receptor, tumor size, body mass index at diagnosis, stage of cancer, and baseline treatment were found to have a significant effect on time to survive for women with breast cancer at the University of Jimma Medical Center, Oromia region, Ethiopia. However, the covariate histologic grade, number of positive lymph nodes involved, and type of hormone used were insignificant to the survival of breast cancer patients.

Influence of stage and grade of breast cancer on fertility preservation outcome in reproductive-aged women.

RESEARCH QUESTION: Does breast cancer spread and aggressiveness affect fertility-preservation results? DESIGN: Retrospective cohort study of women with breast cancer undergoing fertility-preservation treatment. INCLUSION CRITERIA: age 18-38 years and use of gonadotrophin releasing hormone antagonist protocol; exclusion criteria: recurrent cancer, previous oncological treatment, previous ovarian surgery and known ovarian pathology. Stimulation cycle outcomes of women with low-stage breast cancer were compared with those with high-stage disease. Patients with low-grade (G1-2) were compared with those with high-grade (G3) malignancies. PRIMARY OUTCOME: total number of mature oocytes; secondary outcomes: oestradiol level and number of follicles wider than 14 mm on the day of trigger, number of retrieved oocytes and cryopreserved embryos. RESULTS: The final analysis included 155 patients. Patients with high-grade tumours (n = 80; age 32 years [28-35]) had significantly lower number of mature oocytes compared with patients with low-grade cancer (n = 75; age 32 years [28-35]; seven mature oocytes [4-10] versus 13 mature oocytes [7-17]; P = 0.0002). The number of cryopreserved embryos was also lower in the high-grade group (three [2-5] versus five [3-9]; P = 0.02). Stage-based analysis revealed a similar number of mature oocytes in high-stage (n = 73; age 32 years [28-35]) compared with low-stage group (n = 82; age 33 years [28-35]; eight mature oocytes [4-13] versus nine mature oocytes [7-15]; P = 0.06). CONCLUSIONS: High-grade breast cancer has a negative effect on total number of mature oocytes and cryopreserved embryos.

Effects of cancer stage and grade on fertility preservation outcome and ovarian stimulation response.

STUDY QUESTION: Do the stage and grade of malignancy affect the fertility preservation outcome in females? SUMMARY ANSWER: Patients with high-grade cancer have a decreased number of retrieved mature oocytes and cryopreserved embryos. WHAT IS KNOWN ALREADY: Cancer has local and systemic effects on the host. The effects of cancer spread and aggressiveness on the ovarian function and stimulation response remain unclear. STUDY DESIGN, SIZE, DURATION: Retrospective cohort study evaluating data of all fertility preservation treatment cycles among women with cancer at the reproductive unit of the McGill University Health Centre in the period from 2008 to 2017. PARTICIPANTS/MATERIALS, SETTING, METHODS: Study inclusion criteria were age 18-38 years, first stimulation cycle, GnRH-antagonist protocol and early follicular phase stimulation start. Only one stimulation cycle per patient was included. Patients with ovarian pathology, previous ovarian surgery and previous chemo- or radiotherapy were excluded. The outcomes of women with low-stage cancer (local tumor Stage I-II, no lymph node involvement, no metastases) were compared with those with high-stage disease (local tumor Stage III-IV, lymph node involvement or metastases). Similarly we compared those with low-grade (G1-2) and high-grade (G3-4) malignancies. The primary outcome measure was the number of mature oocytes retrieved. The secondary outcomes included the total number of retrieved oocytes, the number of vitrified oocytes, and the number of frozen embryos. We used Student's t-test for normally distributed data and Wilcoxon test for skewed data. To determine factors associated with good fertility preservation outcome defined as over 10 retrieved mature oocytes, we used multivariate logistic regression. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 147 patients were included in the final analysis. Age, body mass index, ovarian reserve parameters of the study groups in stage- and grade-based analyses were similar. Compared to women with low-stage cancer (n = 83), those with high-stage cancer (n = 64) required a higher dose of gonadotropin (P = 0.02). The number of retrieved mature oocytes (9 (7-13) versus 8 (5-12); P = 0.37) and vitrified oocytes (10 (7-15) versus 10 (7-13); P = 0.53) were similar between the two groups. However, in cycles where fertilization of all retrieved oocytes was performed, the fertilization rate (82.7% versus 71.5%; P = 0.03) and the number of vitrified embryos (6.2 ± 3.2 versus 4.3 ± 2.1; P = 0.01) were higher in the low-stage group. Compared to patients with low-grade cancer (n = 62), those with high-grade disease (n = 85) had significantly lower number of retrieved mature oocytes (11 (7-15) versus 8 (5-11); P = 0.002) and vitrified oocytes (12 (8-15) versus 10 (7-11); P = 0.005). The number of vitrified embryos was lower in high-grade group (6.5 ± 3.5 versus 4.6 ± 2.3; P = 0.03) in cycles where the fertilization was performed. In multivariate logistical analysis, the low-grade cancer was significantly associated with retrieval of over 10 mature oocytes (OR = 4.26; 95% CI 1.82-9.98; P = 0.0009). LIMITATIONS, REASONS FOR CAUTION: The main limitations of the study include its retrospective design and the relatively small sample size in the embryological outcome analysis. The results of our study should be viewed with caution as different malignancy types were included in the study groups, although their distribution between the study groups was similar. WIDER IMPLICATIONS OF THE FINDINGS: Cancer grade seems to have a negative impact on the fertility preservation outcome and the ovarian stimulation response.

The Meaning of Hope for Polish Male Patients Dying from Cancer Depending on Their Age: An Interdisciplinary Study with the Use of Osgood's Semantic Differential Method.

Background/Objectives: The subject of this article is the reflection on hope-one of the most important predictors and motivators of human actions. Hope is our response to a threat, and it is also the emotion that allows us to overcome hopelessness and to reduce suffering. Hoping is a human capacity with varying cognitive, emotional, and functional dimensions. Psychological, pedagogical (particularly in the framework of special-needs pedagogy and thanatological pedagogy), and theological reflection on hope can be helpful for dying people. The objective of this study was to characterize hope in the semantic space of individuals in the terminal stage of cancer and to verify whether age is a variable that determines this hope. Methods: To complete the study, the Osgood semantic differential method was applied, as modified by Polish psychologist Dr. Boguslaw Block (the DSN-3 test). The research technique consisted of a therapeutic conversation. Results: Research results show that, in general, those in the terminal stage have positive associations with hope. In all three aspects of the used test, namely the cognitive, emotional, and functional aspects, the highest scores assigned to the perception of hope were obtained from men up to 35 years of age. Depending on the ages of patients, one could observe certain semantic shifts, but they did not prove to be statistically significant. Conclusions: Polish males surveyed at the end of life due to cancer generally perceived hope as a supportive force. Therefore, hope can provide emotional support to patients in the terminal stage of cancer and improve their quality of life.

The Cognitive Aspect of Hope in the Semantic Space of Male Patients Dying of Cancer.

The aim of this study is to characterize the cognitive aspect of the semantic space of hope in patients in the terminal stage of cancer. This was confirmed in the research on hope by C. R. Snyder and B. Schrank. Hope is of great importance in all the great world religions and belief systems, both as regards a personal God or impersonal deities. Hoping is a human capacity with varying affective, cognitive and behavioral dimensions. Psychological, pedagogical (particularly in the framework of special needs pedagogy and thanatological pedagogy) and theological reflection on hope can provide support for dying people. In order to conduct the research, the semantic differential research method was selected. The research technique employed was a therapeutic conversation, and the research tool was the B.L. Block's DSN-3 test. The DSN-3 test allows one to assess hope in the semantic space in three aspects: cognitive, emotional and functional. For the purposes of this study, only the cognitive aspect was taken into account. The study was begun on 1 April 2010 and ended in the last days of December 2020. It included 110 male patients in the terminal stage of cancer. The youngest respondent was 19 years old and the oldest was 94 years old. The surveyed men most often perceived hope in the semantic space in the cognitive aspect as more true, wise, meaningful and real than false, stupid, meaningless and deceptive. Their attitude to hope was, therefore, more affirmative than negative. The research did not reveal the importance of the age of the respondents on the degree of affirmation/negation of hope in the cognitive aspect in the semantic space; however, men in the period of late maturity and professional activity expressed the lowest level of the affirmation of hope. It is worthwhile to conduct further research concerning hope in other aspects (especially emotional and functional) in the semantic space in order to use the obtained results to consider what to take into account when providing patients in the terminal stage of cancer with better personalized holistic care than before.

Identifying Patient Populations in Texts Describing Drug Approvals Through Deep Learning-Based Information Extraction: Development of a Natural Language Processing Algorithm.

BACKGROUND: New drug treatments are regularly approved, and it is challenging to remain up-to-date in this rapidly changing environment. Fast and accurate visualization is important to allow a global understanding of the drug market. Automation of this information extraction provides a helpful starting point for the subject matter expert, helps to mitigate human errors, and saves time. OBJECTIVE: We aimed to semiautomate disease population extraction from the free text of oncology drug approval descriptions from the BioMedTracker database for 6 selected drug targets. More specifically, we intended to extract (1) line of therapy, (2) stage of cancer of the patient population described in the approval, and (3) the clinical trials that provide evidence for the approval. We aimed to use these results in downstream applications, aiding the searchability of relevant content against related drug project sources. METHODS: We fine-tuned a state-of-the-art deep learning model, Bidirectional Encoder Representations from Transformers, for each of the 3 desired outputs. We independently applied rule-based text mining approaches. We compared the performances of deep learning and rule-based approaches and selected the best method, which was then applied to new entries. The results were manually curated by a subject matter expert and then used to train new models. RESULTS: The training data set is currently small (433 entries) and will enlarge over time when new approval descriptions become available or if a choice is made to take another drug target into account. The deep learning models achieved 61% and 56% 5-fold cross-validated accuracies for line of therapy and stage of cancer, respectively, which were treated as classification tasks. Trial identification is treated as a named entity recognition task, and the 5-fold cross-validated F1-score is currently 87%. Although the scores of the classification tasks could seem low, the models comprise 5 classes each, and such scores are a marked improvement when compared to random classification. Moreover, we expect improved performance as the input data set grows, since deep learning models need to be trained on a large enough amount of data to be able to learn the task they are taught. The rule-based approach achieved 60% and 74% 5-fold cross-validated accuracies for line of therapy and stage of cancer, respectively. No attempt was made to define a rule-based approach for trial identification. CONCLUSIONS: We developed a natural language processing algorithm that is currently assisting subject matter experts in disease population extraction, which supports health authority approvals. This algorithm achieves semiautomation, enabling subject matter experts to leverage the results for deeper analysis and to accelerate information retrieval in a crowded clinical environment such as oncology.

Difficulties in Addressing Artificial Hydration and Nutrition Therapy for Terminal Cancer Patients: What to do if Patients/Families' Wishes Differ From the Medically Appropriate Treatment Plans?

PURPOSE: Artificial hydration and nutrition therapy (AHNT) initiated by patients/families sometimes differs from medically appropriate treatment plans. We aimed to identify the causes of these differences and examine the ensuing responses and outcomes. METHODS: Of 133 adult cancer patients receiving end-of-life care in the last 2 years, these discrepancies occurred in 41 patients. We retrospectively examined the following issues: (1) The reason why these discrepancies occurred. (2) Based on the causes identified in (1), the following actions were taken: 1) If the consent to change to medically appropriate AHNT was obtained, physical findings using Japan Palliative Oncology Study (JPOS) group and Edmonton Symptom Assessment System (ESAS) were compared before and 1 week after the intervention. 2) If consent was not obtained, time-limited trial (TLT) was conducted, and these results were compared. (3) The communication between patients/families and medical professionals was compared using Support Team Assessment Schedule. RESULTS: (1) Causes: a) the lack of understanding of the disease condition in 26 cases and b) faulty expectation of AHNT in 15 cases. (2) In 30 cases of 1) (20 of a) and 10 of b)) and 11 of 2) in which TLT was performed, JPOS and ESAS improved significantly. (3) The communication above was improved significantly in 1) and 2) (P = .0027 and .0039, respectively). CONCLUSION: Providing medically appropriate AHNT with the consent of patients/families is expected to not only alleviate distressing symptoms but also improve the communication between patients/families and medical professionals, as well as improve the quality of palliative care.

Identification of key classification features of early cervical squamous cell carcinoma.

Despite the tremendous progress in molecular analysis of pan-cancer, little is known regarding molecular classification of cervical squamous cell carcinoma. In this study, we adopted a multi-omics approach to identify potential key classification features of cervical squamous cell carcinoma. Specifically, we analyzed mRNA, and microRNA (miRNA) expression data, as well as DNA methylation and copy number variation in cervical squamous cell carcinoma cases, using datasets obtained from The Cancer Genome Atlas (TCGA). Moreover, we identified molecules in each dimension, as well as integrated and clustered filtered classification features, and used them to distinguish different subtypes. The resulting key classification features were used to establish a classification model for cervical squamous cell carcinoma. Our results revealed two cervical squamous cell carcinoma subtypes, with significant differences across clinical survival levels, as well as 8 key classification features of cervical squamous cell carcinomas. These findings are expected to provide important references for early classification of cervical squamous cell carcinoma and identification of classification markers.

Impact of extent and biochemical parameters of lymphoma on fertility preservation outcome.

OBJECTIVE: To evaluate the impact of lymphoma aggressiveness on ovarian response during fertility preservation treatment. DESIGN: Retrospective cohort study. SETTING: University-affiliated tertiary hospital. PATIENT(S): Women with lymphoma who underwent ovarian stimulation for fertility preservation in the period from 2009 to 2018. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Primary outcome: the number of mature oocytes; secondary outcomes: the number of retrieved oocytes, estradiol level, and number of follicles >14 mm on the day of oocyte maturation trigger. RESULT(S): Patients with stage I-II lymphoid neoplasms (localized disease) were compared with those with stage III-IV lymphomas (advanced disease). Women with favorable levels of biochemical prognostic markers were also compared with those with unfavorable levels. Women with favorable levels of biochemical prognostic markers (n = 74) had a higher number of mature oocytes compared with patients with unfavorable serum levels (n = 67): 11 (7.8-16) versus 9 (5-11), respectively. The number of mature oocytes was similar between patients with localized (n = 75) and advanced (n = 66) lymphomas. Women with unfavorable combination of stage and biochemical factors had lower number of mature oocytes compared to patients with favorable combination: 8 (5-10) versus 11 (7-16), respectively. Multivariate logistic regression showed that favorable levels of biochemical markers as well as a combination of extent and biochemical parameters were statistically significantly associated with the result of over 10 mature oocytes. CONCLUSION(S): Highly-aggressive lymphoid neoplasms have a negative impact on ovarian function and response during fertility preservation treatment.

Self-controllable prodromal symptoms of syncope attributed to carotid sinus syndrome during the end stage of cancer: a case report.

BACKGROUND: Carotid sinus syndrome (CSS) can cause prodromal symptoms of syncope such as dizziness and nausea. Patients with end-stage cancer lose self-efficacy associated with reduced activities of daily life (ADL). Herein, we report a case of end-stage cancer in which self-efficacy was enhanced as the patient gained self-control of prodromal symptoms of syncope. CASE PRESENTATION: A 70-year-old patient with end-stage esophageal cancer and enlarged supraclavicular lymph nodes developed CSS. The CSS was a mixed type with both bradycardia and decreased blood pressure, accompanied by prodromal symptoms prior to syncope episodes. The patient incidentally discovered that he could decrease the duration of symptoms by contracting the muscles in his hands and legs. By applying this coping method at the onset of prodromal symptoms, he was also able to reduce the severity and duration of symptoms, which resulted in enhanced self-efficacy. As a result, the frequency of prodromal symptoms also decreased even though ADL improved. CONCLUSION: This patient was diagnosed with vasoinhibitory-predominant mixed-type CSS. The coping method the patient developed seemed to avoid the onset of abrupt blood pressure decrease via peripheral vascular constriction action. Achievement of adequate coping such as self-control of prodromal symptoms enabled our patient to improve his self-efficacy even at the end stages of cancer. This case of enhanced self-efficacy could possibly illustrate a placebo effect for prevention of recurrence.
