Background: The complication rate of fungal disease is higher among patients with hematological malignancies. We investigated the clinicobacteriological outcomes of resected pulmonary fungal infections complicating hematological malignancies. Methods: Between 2001 and 2017, 21 patients with pulmonary fungal infections complicating hematological malignancies underwent resection, and their clinical records and survival were retrospectively reviewed. Results: The median age of the patients was 47 years, and 13 were male. The histological diagnoses were pulmonary aspergillosis (19 cases), mucormycosis (1 case), and cryptococcosis (1 case). The indications for surgery were resistance to antifungal therapy and the necessity of surgery before hematopoietic stem cell transplantation in 13 and 8 cases, respectively. The diagnoses of the hematological malignancies were acute myelogenous leukemia (10 cases), acute lymphocytic leukemia (5 cases), myelodysplastic syndrome (3 cases), and chronic myelogenous leukemia, malignant lymphoma, and extramedullary plasmacytoma (1 case each). The surgical procedures were partial resection (11 cases), segmentectomy (5 cases), lobectomy (4 cases), and cavernostomy (1 case). The size of the lesions was 0.9-8.5 cm. Fourteen cases had cavitation. There were no surgical-related deaths or fungal progression. Conclusion: Pulmonary fungal infections are resistant to treatments for hematological malignancies. Since the treatment of the underlying disease is extended and these infections often recur and are exacerbated, surgery should be considered when possible.

Background: Diagnostic difficulties in hematological malignancies may lead to unacceptably prolonged help-seeking to diagnostic interval as well as increased complications and poor outcomes. Proactive consultation by a clinical pathologist (PCCP) may help clinical diagnosis and therapeutic strategy. Hence, the aim of this investigation was to evaluate the effect of PCCP on the help-seeking to diagnostic interval in hematological cancer cases. Materials and Methods: From January to November, 2015, abnormal results of hematological laboratory testing with added laboratory comment were selectively screened out, and patients with such abnormalities in hematological laboratory testing and accompanied laboratory comment with PCCP were enrolled. Results: A total of 125 aberrant results of hematological laboratory testing were given with accompanied laboratory comments with PCCP and 40.8% (n=51) of these patient-oriented comments had an effect on clinical diagnosis and therapeutic strategy. Twelve of the subjects belonged to newly diagnosed hematological malignancies with the assistance of PCCP, and the help-seeking to diagnostic interval was also shortened from 42 days to 26 days in chronic lymphoid leukemia (CLL), from 83 days to 11 days in multiple myeloma (MM), and from 128 days to 15 days in myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN). During the monitoring interval, neither complication events nor deaths were reported in the study group. Conclusions: It was seemingly that PCCP prevented diagnostic delay in hematological malignancies via shortening the help-seeking to diagnostic interval, particularly in CLL, MM and MDS/MPN cases. PCCP can be considered to play an essential role in prompt establishment of diagnosis in hematological malignancies for those who newly present.

Objective: Based on the Liver Imaging Reporting and Data System version 2018 (LI-RADS, v2018), this study aimed to analyze LR-5 diagnostic performance for hepatocellular carcinoma (HCC) when threshold growth as a major feature is replaced by a more HCC-specific ancillary feature, as well as the frequency of threshold growth in HCC and non-HCC malignancies and its association with tumor size. Materials and Methods: This retrospective study included treatment-naive patients who underwent gadoxetate disodium-enhanced MRIs for focal hepatic lesions and surgery between January 2009 and December 2016. The frequency of major and ancillary features was evaluated for HCC and non-HCC malignancies, and the LR-category was assessed. Ancillary features that were significantly more prevalent in HCC were then used to either replace threshold growth or were added as additional major features, and the diagnostic performance of the readjusted LR category was compared to the LI-RADS v2018. Results: A total of 1013 observations were analyzed. Unlike arterial phase hyperenhancement, washout, or enhancing capsule which were more prevalent in HCCs than in non-HCC malignancies (521/616 vs. 18/58, 489/616 vs. 19/58, and 181/616 vs. 5/58, respectively; p < 0.001), threshold growth was more prevalent in non-HCC malignancies than in HCCs (11/23 vs. 17/119; p < 0.001). The mean size of non-HCC malignancies showing threshold growth was significantly smaller than that of non-HCC malignancies without threshold growth (22.2 mm vs. 42.9 mm, p = 0.040). Similar results were found for HCCs; however, the difference was not significant (26.8 mm vs. 33.1 mm, p = 0.184). Additionally, Fat-in-nodule was more frequent in HCCs than in non-HCC malignancies (99/616 vs. 2/58, p = 0.010). When threshold growth and fat-in-nodule were considered as ancillary and major features, respectively, LR-5 sensitivity (73.2% vs. 73.9%, p = 0.289) and specificity (98.2% vs. 98.5%, p > 0.999) were comparable to the LI-RADS v2018. Conclusion: Threshold growth is not a significant diagnostic indicator of HCC and is more common in non-HCC malignancies. The diagnostic performance of LR-5 was comparable when threshold growth was recategorized as an ancillary feature and replaced by a more HCC-specific ancillary feature.

Although the survival rate of hematologic malignancies in young patients is very high, cytotoxic therapies such as chemotherapy and total body irradiation therapy can significantly reduce a patient's reproductive capacity and cause irreversible infertility. Early ovarian failure also commonly occurs following additional cancer treatment, bone marrow transplantation, or autologous transplantation. Because the risk of early ovarian failure depends on the patient's circumstances, patients with a hematologic malignancy must consult health professionals regarding fertility preservation before undergoing treatments that can potentially damage their ovaries. While it is widely known that early menopause commonly occurs following breast cancer treatment, there is a lack of reliable study results regarding fertility preservation during hematologic malignancy treatment. Therefore, an in-depth discussion between patients and health professionals about the pros and cons of the various options for fertility preservation is necessary. In this study, we review germ cell toxicity, which occurs during the treatment of hematologic malignancies, and propose guidelines for fertility preservation in younger patients with hematologic malignancies.

Purpose: This study was aimed to identify the incidence and severity of chemotherapy-induced peripheral neuropathy (CIPN) among patients with hematologic malignancies and to examine the relationship between the quality of life (QOL) and CIPN. Methods: A total of 66 patients with CIPN-related symptoms participated in this study. Data were collected through self-reported questionnaires consisted of the European Organization for Research and Treatment of Cancer QLQ-C30 version 3.0 and the 16-item QLQ-CIPN20. Data were analyzed with SPSS/WIN20 for descriptive statistics using the Mann-Whitney and Kruskal-Wallis tests, and Spearman's rho. Results: The mean lower and upper extremity scale scores were 31.95 and 23.16 respectively for the 16-item QLQ-CIPN20. The mean QLQ-C30 subcategory scores were 46.84 for global health status, 58.72 for functional scales, and 34.85 for symptom scales. The CIPN-related lower extremity scale symptoms correlated negatively with the QOL subscales. There was no correlation between CIPN-related upper extremity symptoms and health-related QOL. Conclusion: Patients with hematologic malignancies treated with neurotoxic chemotherapeutic agents had CIPN-related symptoms in the lower extremities mainly, and their QOL functional subscale scores were relatively lower than those of other cancer patients. Interventions need to be developed for patients with hematologic malignancies to alleviate CIPN and enhance their QOL.

RUNX1 plays an important role in the regulation of normal hematopoiesis. RUNX1 mutations are frequently found and have been intensively studied in hematological malignancies. Germline mutations in RUNX1 cause familial platelet disorder with predisposition to acute myeloid leukemia (FPD/AML). Somatic mutations of RUNX1 are observed in various types of hematological malignancies, such as AML, acute lymphoblastic leukemia (ALL), myelodysplastic syndromes (MDS), myeloproliferative neoplasm (MPN), chronic myelomonocytic leukemia (CMML), and congenital bone marrow failure (CBMF). Here, we systematically review the clinical and molecular characteristics of RUNX1 mutations, the mechanisms of pathogenesis caused by RUNX1 mutations, and potential therapeutic strategies to target RUNX1-mutated cases of hematological malignancies.

Diabetic foot wounds have a significant effect on the health-related quality of life of patients. As diabetic foot wounds are usually chronic and recurrent, it is possible that they can lead to skin malignancies. Several factors can make it difficult to make an early and accurate diagnosis of skin malignancies of the foot in patients with diabetes mellitus. Even though the prevalence of diabetes mellitus and diabetic foot wounds is increasing, currently there are no guidelines for the biopsy of diabetic foot wounds. We have evolved a criterion for the above based on six cases of diabetic foot wounds with concomitant skin malignancies. We recommend that clinicians should broadly consider implementing this criterion when managing patients with diabetic foot wounds.

Objective: To determine the accuracy of magnetic resonance imaging (MRI) in detection of metastasis in pelvic and para-aortic lymph nodes from different gynecological malignancies. Materials and Methods: This retrospective cross sectional analytic study was conducted at the Department of Diagnostic Radiology, Aga Khan University Hospital Karachi Pakistan from January 2011 to December 2012. A sample of 48 women, age range between 20-79 years, fulfilling inclusion criteria were included. All patients had histopathologically proven gynecological malignancies in the cervix, endometrium or ovary and presented for a pretreatment MRI to our radiology department. Results: MRI was 100% sensitive and had a 100% positive predictive value to detect lymph node metastasis in lymph nodes with spiculated margins and 100% sensitive with a 75% positive predictive value to detect lymph node metastasis in a lymph node with lobulated margins. The sensitivity and positive predictive value of MRI to detect heterogeneous nodal enhancement were 100% and 75% respectively. Conclusions: Our study results reinforce that MRI should be used as a modality of choice in the pretreatment assessment of lymph nodes in proven gynaecological malignancies in order to determine the line of patientmanagement, distinguishing surgical from non-surgical cases.

Catheter related and perianal problems are common surgical complications encountered during the treatment of pediatric malignancies. However acute surgical abdominal emergencies are rare. The aim of this study is to review acute surgical abdominal complications that occur during the treatment of childhood malignancies. Out of a total of 1,222 patients who were newly diagnosed with malignant disease, between January 2003 and May 2008, there were 10 patients who required surgery because of acute abdominal emergencies. Their medical records were reviewed retrospectively. Hematologic malignancies were present in 7 patients (4 leukemia, 2 lymphoma, 1 Langerhans cell histiocytosis) and solid tumors in 3 patients (1 adrenocortical carcinoma, 1 desmoplastic small round cell tumor, 1 rhabdomyosarcoma). Seven patients had intestinal obstruction, two had gastrointestinal perforation and one, typhlitis. Intestinal obstructions were treated with resection of the involved segment with (N=2) or without (N=3) enterostomy. Two patients had enterostomy alone when resection could not be performed. Intestinal perforation was treated with primary repair. Typhlitis of the ascending colon was treated with ileostomy. Right hemicolectomy was necessary the next day because of the rapidly progressing sepsis. Three patients are now alive on chemotherapy and one patient was lost to followed-up. Among six patients who died, five died of their original disease progression and one of uncontrolled sepsis after intestinal perforation. Although rare, acute surgical abdominal complications can occur in childhood malignancies. Rapid and accurate diagnosis and appropriate operation are required for effective treatment of the complications.
