Rural and Urban patients' Requirements and Experiences of Out-of-hours medical care after cancer (RUREO): a questionnaire study.

OBJECTIVE: To investigate how individuals diagnosed with cancer use out-of-hours (OOH) medical services, describe the behavioural determinants of OOH service use and explore whether there are differences between urban and rural dwellers. DESIGN AND SETTING: A cross-sectional questionnaire study conducted in Northeast Scotland. PARTICIPANTS: The questionnaire was sent to 2549 individuals diagnosed with cancer in the preceding 12 months identified through the National Health Service Grampian Cancer Care Pathway database. 490 individuals returned the questionnaire (19.2% response rate), 61.8% were urban and 34.9% were rural. OUTCOMES: Outcomes were differences in frequency of medical service use and attitudes towards OOH services between urban and rural participants. Patient experience (qualitative data) was compared. RESULTS: Daytime services were used much more frequently than OOH services-83.3% of participants had never contacted an OOH primary care service in the preceding 12 months but 44.2% had used their daytime general practitioner at least four times. There were no significant differences between urban and rural dwellers in the patterns of OOH or daytime service use, the behavioural determinants of service use or the experiences of OOH services. Rural dwellers were significantly less likely to agree that OOH services were close by and more likely to agree that where they lived made it difficult to access these services. Rural dwellers were no more likely to agree or disagree that distance would affect their decision to contact OOH services. Qualitative results highlighted barriers to accessing OOH services exist for all patients but that long travel distances can be offset by service configuration, travel infrastructure and access to a car. CONCLUSIONS: Urban and rural dwellers have similar beliefs, attitudes towards and patterns of OOH service use. In Northeast Scotland, place of residence is unlikely to be the most important factor in influencing decisions about whether to access OOH medical care.

Treatment burden in individuals living with and beyond cancer: A systematic review of qualitative literature.

BACKGROUND: Individuals with cancer are being given increasing responsibility for the self-management of their health and illness. In other chronic diseases, individuals who experience treatment burden are at risk of poorer health outcomes. Less is known about treatment burden and its impact on individuals with cancer. This systematic review investigated perceptions of treatment burden in individuals living with and beyond cancer. METHODS AND FINDINGS: Medline, CINAHL and EMBASE databases were searched for qualitative studies that explored treatment burden in individuals with a diagnosis of breast, prostate, colorectal, or lung cancer at any stage of their diagnostic/treatment trajectory. Descriptive and thematic analyses were conducted. Study quality was assessed using a modified CASP checklist. The review protocol was registered on PROSPERO (CRD42021145601). Forty-eight studies were included. Health management after cancer involved cognitive, practical, and relational work for patients. Individuals were motivated to perform health management work to improve life-expectancy, manage symptoms, and regain a sense of normality. Performing health care work could be empowering and gave individuals a sense of control. Treatment burden occurred when there was a mismatch between the resources needed for health management and their availability. Individuals with chronic and severe symptoms, financial challenges, language barriers, and limited social support are particularly at risk of treatment burden. For those with advanced cancer, consumption of time and energy by health care work is a significant burden. CONCLUSION: Treatment burden could be an important mediator of inequities in cancer outcomes. Many of the factors leading to treatment burden in individuals with cancer are potentially modifiable. Clinicians should consider carefully what they are asking or expecting patients to do, and the resources required, including how much patient time will be consumed.

Treatment burden in survivors of prostate and colorectal cancers: a qualitative interview study.

OBJECTIVES: Treatment burden is the workload of healthcare and the impact this has on the individual. Treatment burden is associated with poorer patient outcomes in several chronic diseases. Illness burden has been extensively studied in cancer, but little is known about treatment burden, particularly in those who have completed primary treatment for cancer. The aim of this study was to investigate treatment burden in survivors of prostate and colorectal cancers and their caregivers. DESIGN: Semistructured interview study. Interviews were analysed using Framework and thematic analysis. SETTING: Participants were recruited via general practices in Northeast Scotland. PARTICIPANTS: Eligible participants were individuals who had been diagnosed with colorectal or prostate cancer without distant metastases within the previous 5 years and their caregivers. Thirty-five patients and six caregivers participated: 22 patients had prostate and 13 had colorectal cancers (six male, seven female). RESULTS: The term 'burden' did not resonate with most survivors, who expressed gratitude that time invested in cancer care could translate into improved survival. Cancer management was time consuming, but workload reduced over time. Cancer was usually considered as a discrete episode. Individual, disease and health system factors protected against or increased treatment burden. Some factors, such as health service configuration, were potentially modifiable. Multimorbidity contributed most to treatment burden and influenced treatment decisions and engagement with follow-up. The presence of a caregiver protected against treatment burden, but caregivers also experienced burden. CONCLUSIONS: Intensive cancer treatment and follow-up regimens do not necessarily lead to perceived burden. A cancer diagnosis serves as a strong motivator to engage in health management, but a careful balance exists between positive perceptions and burden. Treatment burden could lead to poorer cancer outcomes by influencing engagement with and decisions about care. Clinicians should ask about treatment burden and its impact, particularly in those with multimorbidity. TRIAL REGISTRATION NUMBER: NCT04163068.

Cytologic analysis of vitreous fluids: A retrospective review of our 24 years of experience.

BACKGROUND: Cytologic analysis of vitreous fluid is an important component in diagnosis of vitreitis. No standard reporting guidelines exist for these specimens. This study chronicles our 24 years experience and proposes a tentative diagnostic model. METHODS: Retrospective cytology reports review and database study. Clinical indications, cytologic patterns, ancillary studies performed, and diagnoses were recorded. RESULTS: 176 samples from 160 patients were included and main cytologic patterns are reflected in Table 1. Most fluids were negative for malignancy (88%) and patterns IIB (53%) and IIA (19%) were dominant. The non-diagnostic rate was 7%; atypical and suspicious categories represented <0.5% of fluids tested and only 2% were positive for malignancy (3 intraocular lymphoma and one melanoma). Clinical indications for fluid examination were infection/inflammation (59%), to rule out lymphoma (11%), amyloidosis (3%), melanoma (2%), or to investigate intraocular hemorrhage. Fungal elements were demonstrated in 7 cases. No viral inclusions were appreciated; however, one case was positive for HSV 2 by IHC and 2 were negative by PCR. One case had Gram + cocci. Flow cytometry studies were suboptimal in 6 fluids, negative for an aberrant lymphocyte population in 11, and positive for high grade lymphoma in 3 cases. Atypical, suspicious and positive for melanoma were reported in 3 samples. Amyloid was identified in 1 aspirate. CONCLUSIONS: Cytologic analysis of vitreous fluid is a useful tool. Modern techniques like flow cytometry and PCR testing further expand the diagnostic possibilities. Standardization of diagnostic terminology will aid clinicians caring for patients suffering from ocular disease.

Hematopoietic Cell Transplantation and Outcomes Related to Human Papillomavirus Disease in GATA2 Deficiency.

GATA2 deficiency is a bone marrow failure syndrome effectively treated with hematopoietic cell transplantation (HCT), which also addresses the predisposition to many infections (prominently mycobacterial). However, many GATA2-deficient persons who come to HCT also have prevalent and refractory human papilloma virus disease (HPVD), which can be a precursor to cancer. We analyzed 75 HCT recipients for the presence of HPVD to identify patient characteristics and transplantation results that influence HPVD outcomes. We assessed the impact of cellular recovery and iatrogenic post-transplantation immunosuppression, as per protocol (PP) or intensified/prolonged (IP) graft-versus-host disease (GVHD) prophylaxis or treatment, on the persistence or resolution of HPVD. Our experience with 75 HCT recipients showed a prevalence of 49% with anogenital HPVD, which was either a contributing or primary factor in the decision to proceed to HCT. Of 24 recipients with sufficient follow-up, 13 had resolution of HPVD, including 8 with IP and 5 with PP. Eleven recipients had persistent HPVD, including 5 with IP and 6 with PP immunosuppression. No plausible cellular recovery group (natural killer cells or T cells) showed a significant difference in HPV outcomes. One recipient died of metastatic squamous cell carcinoma, presumably of anogenital origin, at 33 months post-transplantation after prolonged immunosuppression for chronic GVHD. Individual cases demonstrate the need for continued aggressive monitoring, especially in the context of disease prevalent at transplantation or prior malignancy. HCT proved curative in many cases in which HPVD was refractory and recurrent prior to transplantation, supporting a recommendation that HPVD should be considered an indication rather than contraindication to HCT, but post-transplantation monitoring should be prolonged with a high level of vigilance for new or recurrent HPVD.

Pleomorphic undifferentiated aortic sarcoma presenting as persistent endoleak after endovascular aneurysm repair.

Sarcomas of the aorta are rare tumors with an unknown incidence and wide variety of clinical presentations. These malignant neoplasms are often manifested in an advanced state and with symptoms of nonmalignant vascular disease owing to a delay in diagnosis. We present the case of a 78-year-old man in whom workup was initially performed for a persistently enlarging abdominal aortic aneurysm after endovascular aortic repair but who was subsequently found to have a pleomorphic undifferentiated sarcoma of the aorta.

p16 immunohistochemistry can be used to detect human papillomavirus in oral cavity squamous cell carcinoma.

PURPOSE: Human papillomavirus (HPV) is of etiologic significance in the development of oral squamous carcinoma and is noted to result in p16 overexpression. Identification of HPV is clinically important because the presence of HPV has prognostic and epidemiologic associations. Detection of HPV by polymerase chain reaction (PCR) is expensive and not widely accessible. The authors examined p16 immunohistochemistry (IHC) as a surrogate marker for high-risk HPV and its use as an alternative test to PCR. PATIENTS AND METHODS: A retrospective cohort of patients with oral squamous cell carcinoma underwent surgery and then analysis with p16 IHC and HPV PCR. The p16 IHC staining intensity was graded from 0 to 3+, and these results were compared with PCR. Descriptive and frequency statistics were performed by comparing HPV PCR results with p16 IHC, patient age, gender, and outcome. RESULTS: Eighty-one cases were included in the study. Forty-four study patients were men and 37 were women (mean age, 63.9 yr). Forty-five cases (55.6%) had 0 staining, 22 cases (27.2%) had 1+ staining, and 7 cases (8.6%) had 2+ staining. Seven cases (8.6%) had 3+ staining, all of which were positive for HPV serotype 16 by PCR. Three of 7 HPV PCR-positive cases had keratinization typical of an oral cavity location and not the basaloid growth of HPV oropharyngeal tumors. There was a statistical correlation (P < .001) among HPV PCR positivity, 3+ staining, and younger age. CONCLUSION: p16 3+ staining correlates with HPV PCR positivity. p16 IHC is a technically simple and widely available test, and this study establishes the use of p16 IHC as an alternative test to HPV PCR. Given the clinical significance of HPV in oral squamous carcinoma, p16 IHC should be performed in all cases and included in the pathology report.

Prognostic value of breast cancer subtypes, Ki-67 proliferation index, age, and pathologic tumor characteristics on breast cancer survival in Caucasian women.

Estrogen receptor (ER), progesterone receptor (PR), and epidermal growth factor receptor 2 (HER2) status are well-established prognostic markers in breast cancer management. The triple negative breast carcinoma subtype (ER-/PR-/HER2-) has been associated with worse overall prognosis in comparison with other subtypes in study populations consisting of ethnic minorities and young women. We evaluated the prognostic value of breast cancer subtypes, Ki-67 proliferation index (Ki-67PI), and pathologic tumor characteristics on breast cancer survival in Caucasian women in our institution, where greater than 90% of the total patient population is white. From 628 new invasive breast cancer cases in our data base (2000-late 2004), 593 (94%) were identified in Caucasian women. ER/PR/HER2 breast cancer subtypes were classified based on St. Gallen International Expert Consensus recommendations from 2011. ER/PR/HER2 status and its effect on survival were analyzed using a Kaplan-Meier curve. ER/PR/HER2 status, grade, tumor-node-metastasis status (TNM)/anatomic stage, and age were analyzed in terms of survival in a multivariate fashion using a Cox regression. Ki-67PI was analyzed between ER/PR/HER2 groups using the Kruskal-Wallis, Mann-Whitney U-tests, and 2 × 5 ANOVA. Our results showed that patients with stage IIB through stage IV breast carcinomas were 2.1-16 times more likely to die than patients with stages IA-B and IIA disease, respectively (95% CI 1.17-3.81 through 9.68-28.03, respectively), irrespective of ER/PR/HER2 subtype. Similar effect was seen with T2, N2/N3, or M1 tumors in comparison with T1, N0/N1, and M0 tumors. Chances of dying increase approximately 5% for every year increase in age. There was a significant main effect of Ki-67PI between ER/PR/HER2 subtypes, p < .001, but Ki-67PI could not predict survival. In summary, TNM status/anatomic stage of breast carcinomas and age are predictive of survival in our patient population of Caucasian women, but breast carcinoma subtypes and Ki-67 proliferation index are not.

Primary cutaneous melanoma arising in a long-standing irradiated keloid.

Ionizing radiation has been used therapeutically for a variety of clinical conditions, including treatment of hypertrophic keloids. Keloids may rarely be associated with malignancy, but the use of low-dose ionizing radiation is associated with an increased risk of cutaneous malignancies. We describe a case in which a primary desmoplastic melanoma arose in a long-standing, previously irradiated keloid.

Primary subretinal abscess caused by acanthamoeba: clinical and pathologic case report and review of the literature.

PURPOSE: To report the clinical and pathologic findings in a patient with a primary Acanthamoeba subretinal abscess. METHODS: A healthy 40-year-old man was evaluated and treated for a subretinal abscess. A subretinal aspirate was evaluated using hematoxylin-eosin stains and polymerase chain reaction. RESULTS: Results of the histologic examination of the subretinal aspirate demonstrated numerous Acanthamoeba cysts. The diagnosis was confirmed by polymerase chain reaction. The infection was treated with local and systemic antimicrobials. The visual acuity remained stable, and there was no local or systemic spread of the infection. CONCLUSION: To the authors' knowledge, this is the first biopsy-proven case of primary subretinal abscess because of Acanthamoeba. Acanthamoeba should be considered in the differential diagnosis of a subretinal abscess, even in the absence of systemic or corneal symptoms. Aggressive treatment can prevent serious ocular and systemic complications.

Quantifying the extent of invasive carcinoma and margin status in partial mastectomy cases having a gross lesion: is a defined tissue processing protocol needed?

Accurate estimation of disease extent and margin status is critical when evaluating partial mastectomy cases because both are predictors of recurrence. No published standards exist for processing specimens involved by invasive carcinoma, presumably because such cases have a gross lesion. We retrospectively studied 100 partial mastectomy cases and concluded that a standardized tissue mapping protocol is needed to ensure adequate pathologic examination even when a gross lesion is present. When mapped and unmapped findings were compared, 17 cases (10 with ductal and 7 with lobular carcinoma) had an increase in carcinoma size, 12 cases (9 with ductal and 3 with lobular carcinoma) had an increase in pathologic T stage, and positive margins were found in 8 cases (7 with ductal and 1 with lobular carcinoma). We describe our tissue-mapping protocol, and advocate its use as a standardized protocol for processing all partial mastectomy specimens.

Evaluation of thyroid fine-needle aspirations: can ThinPrep be used exclusively to appropriately triage patients having a thyroid nodule?

Thyroid fine-needle aspiration (FNA) represents an ideal management tool for thyroid nodules. ThinPrep is routinely used in preparation of a variety of nongynecologic cytology specimens, including FNA. The authors investigated ThinPrep to determine if its diagnostic accuracy is sufficient to triage patients presenting with a thyroid nodule. ThinPrep (TP) slides from four separate study categories were reviewed in a blind fashion. Twenty-five cases of papillary carcinoma, follicular lesion, Hashimoto's thyroiditis and multinodular goiter were examined retrospectively. Diagnostic accuracy of TP for each diagnostic category was determined relative to the final FNA diagnosis. Of 100 total study cases, 46 (46%) had noncorrelation. Twenty five (25%) of the study cases had noncorrelation as a result of insufficient cellularity. The diagnostic accuracy of TP for papillary carcinoma was 64%, for follicular lesion 24%, for Hashimoto's thyroiditis 72% and for multinodular goiter 56%. Cytologic features of papillary carcinoma, Hashimoto's thryoiditis, and multinodular goiter are preserved in TP slides. Cytologic features of follicular lesion are less predictable in TP slides. When all cases of noncorrelation were examined, we concluded that insufficient or marginal cellularity most often accounts for the discrepancy between TP and CS diagnoses in each study category. If techniques can be established to improve cellularity of TP slides, particularly in follicular lesions, we believe that sufficient diagnostic accuracy can be achieved to result in appropriate patient triage. Additional studies exploring methods to improve TP cellularity are needed before TP can be used as the sole diagnostic test for thyroid FNA.

Endobronchial perineurioma: an unusual soft tissue lesion in an unreported location.

We report the first case of an endobronchial perineurioma, a rare benign neoplasm typically occurring in soft tissue. A 53-year-old nonsmoking female presented with a three-month history of persistent bronchitis. A CT scan followed by bronchoscopy demonstrated an endobronchial lesion involving the left mainstem bronchus. Removal of the lesion by bronchoscopy was accomplished. The tumor was composed of bland spindle cells in a variably collagenized stroma. These cells had long cytoplasmic processes. No mitotic activity or necrosis was observed. Neoplastic cells were immunoreactive for epithelial membrane antigen (EMA), CD34, and claudin-1. Smooth muscle actin (SMA), desmin, and S-100 immunostains were all negative. Based on the morphologic appearance and immunophenotype, a diagnosis of perineurioma was rendered.

Clinical integration of picture archiving and communication systems with pathology and hospital information system in oncology.

The complexity of our current healthcare delivery system has become an impediment to communication among caregivers resulting in fragmentation of patient care. To address these issues, many hospitals are implementing processes to facilitate clinical integration in an effort to improve patient care and safety. Clinical informatics, including image storage in a Picture Archiving and Communication System (PACS), represents a tool whereby clinical integration can be accomplished. In this study, we obtained intraoperative photographs of 19 cases to document clinical stage, extent of disease, disease recurrence, reconstruction/grafting, intraoperative findings not identified by preoperative imaging, and site verification as part of the Universal Protocol. Photographs from all cases were stored and viewed in PACS. Images from many of the cases were presented at our interdepartmental cancer conferences. The stored images improved communication among caregivers and preserved pertinent intraoperative findings in the patients' electronic medical record. In the future, pathology, gastroenterology, pulmonology, dermatology, and cardiology are just a few other subspecialties which could accomplish image storage in PACS. Multidisciplinary image storage in a PACS epitomizes the concept of clinical integration and its goal of improving patient care.

Atypical squamous cells, cannot exclude a high-grade intraepithelial lesion and its clinical significance in postmenopausal, pregnant, postpartum, and contraceptive-use patients.

BACKGROUND: Previous studies have confirmed the low predictive value of a diagnosis of atypical squamous cells, cannot exclude a high-grade squamous intraepithelial lesion (ASC-H) in a Papanicolaou (Pap) smear for subsequent high-grade dysplasia in the postmenopausal age group. It appears plausible that the decrease in estrogen inherent in the postmenopausal state likely produces reactive cytologic atypia, which is misinterpreted as ASC-H. The change in hormone levels observed in pregnant patients, postpartum patients, and contraceptive users, as a corollary, potentially could create a similar diagnostic dilemma. In the current study, the impact of age and altered hormone status on the frequency of ASC-H was assessed to answer the following questions: Is the low predictive value of ASC-H in postmenopausal women an age-related phenomenon, and do other states that result in decreased levels of estrogen relative to progesterone have a similar association? METHODS: Pap smears that were diagnosed as ASC-H were divided into postmenopausal, pregnant, postpartum, and contraceptive-use categories. Each Pap smear slide was reviewed to assess the degree of atrophy and the character of atypical cells. The frequency of high-grade follow-up (histology and/or Digene Hybrid Capture II) in the postmenopausal group was compared with the frequency of high-grade follow-up in the pregnant, postpartum, and contraceptive-use categories using the chi-square test. The pregnant, postpartum, and contraceptive-use categories also were compared statistically among each other with the chi-square test. RESULTS: In total, 195 cases met the criteria for study inclusion. The percentage of patients who had subsequent high-grade follow-up was 22.5% in the postmenopausal group, 79.6% in the pregnant group, 66.7% in the postpartum group, and 60% in the contraceptive-use group. When these data were subjected to the chi-square test, there was a statistically significant difference (P<.0001) between the predictive value of subsequent high-grade follow-up in the postmenopausal group compared with the other patient groups. When the chi-square test was applied to the intercomparison of the pregnant, postpartum, and contraceptive-use categories, there were no significant differences (P > .05) in high-grade follow-up between any of these groups. CONCLUSIONS: The diagnosis of ASC-H in postmenopausal Pap smears has a low predictive value in the subsequent diagnosis of high-grade squamous lesions in stark contrast to the pregnant, postpartum, and contraceptive-use categories. This suggests that age rather than hormone alterations affects the capacity of ASC-H to predict subsequent high-grade squamous intraepithelial lesions. In addition, there are no definite cytomorphologic criteria that can be used to distinguish reliably between benign cellular changes and possible high-grade squamous lesions in these Pap smears. Digene Hybrid Capture II testing, although helpful, does not have 100% correlation with subsequent tissue/Pap smear follow-up and cannot be used alone to triage this group of women for colposcopy.
