Case report: If it is not asthma-think of lymphangioleiomyomatosis in younger female patients.

Lymphangioleiomyomatosis (LAM) is a rare lung disease predominantly affecting women, and it is characterized by the proliferation of smooth muscle cells and cystic lung destruction. LAM diagnosis is challenging due to varied clinical presentations and resemblance to common conditions such as asthma. We present two female cases where LAM was initially misdiagnosed. Case 1 describes a woman treated for asthma-chronic obstruction pulmonary disease overlap syndrome, while also undergoing treatment with vascular endothelial growth factor (VEGF) inhibitor pazopanib for a retroperitoneal leiomyoma, the latter responding well to treatment. Due to progressive dyspnea, pazopanib-induced pneumonitis was suspected. High-resolution computed tomography (HRCT) showed changes compatible with LAM. A revision of biopsies showed that the leiomyoma was in fact a lymphangioleiomyoma, and VEGF-D was increased. Both supported the LAM diagnosis. Treatment with mTORC1 inhibitor sirolimus was initiated. Case 2 describes a woman, who in resemblance with the woman from case 2 was also suspected of asthma and did not respond clinically to treatment. After several years, HRCT was performed and suspicion of LAM was raised. Transbronchial biopsy and later, an increased VEGF-D supported the LAM diagnosis. As in case 1, treatment with sirolimus was initiated. These cases underscore the importance of reevaluating diagnoses when treatments fail to yield expected results. Improved awareness and early detection of LAM can enhance patient outcomes and life quality. Early LAM diagnosis is vital as mTORC1 inhibitors such as sirolimus can prevent further decline in lung function. Notably, the response of case 2 to pazopanib treatment supports suggestions of its potential as a second-line therapy for perivascular epithelioid cell tumors (PEComas), including LAM.

Struggling to Eat to Survive Cancer-Lived Experiences of Eating Among Adolescents and Young Adults Undergoing High-Emetogenic Chemotherapy.

Purpose: The purpose of this study was to provide in-depth understanding of adolescents' and young adults' (AYAs') lived experiences of eating when they are at home between high-emetogenic chemotherapy sessions. Methods: The study was guided by van Manen's hermeneutic-phenomenological methodology. Eligible AYAs were 15-29 years old, diagnosed with either oncological or hematological cancer, treated with high-emetogenic chemotherapy, and Danish speaking. AYAs were recruited from three university hospital departments. Data were collected using semi-structured in-depth interviews. Results: Thirteen AYAs, aged 17-29 years, participated in the interviews via telephone or face-to-face in their homes. The essential meaning of the phenomenon of eating can be characterized by the overarching theme "Struggling to eat to survive" and unfolded through the following three themes: "Cooperating with a deceiving body", "Capturing moments of eating opportunities", and "Being loved and cared for at home". Conclusions: Struggling to eat was essential for survival and a fundamental existential challenge that required reflection and consciousness. AYAs experienced their deceiving bodies as a major concern, which challenged their ability to eat and forced them to develop strategies to capture moments of eating opportunities. AYAs kept hold of doing "something" themselves to maintain the slightest control of their own lives and thereby assist clinical outcomes and cure. However, AYAs had to struggle with food and start viewing food as a friend, not an enemy.

Walking a tightrope - as a next-of-kin to an adolescent or young adult with cancer facing eating difficulties.

PURPOSE: Eating difficulties cause reduced food intake and poor quality of life among adolescents and young adults (AYAs) with cancer. Therefore, next-of-kin eating support is crucial. The purpose of this study was to explore the lived experiences of being close to AYAs with cancer in the context of eating when they are at home between high-emetogenic chemotherapy (HEC) sessions. METHOD: In-depth interviews were conducted with 12 next-of-kin to AYAs (15-29 years old) with oncological or haematological diseases, treated with HEC. Van Manen's hermeneutic-phenomenological approach guided the design. RESULTS: The essential meaning of the next-of-kin experiences is reflected in the overarching theme "Utilizing meals as an action-opportunity" consisting of two subthemes: 'Being on constant alert' and "Walking a tightrope to maintain usual everyday life." CONCLUSIONS: Findings revealed that utilizing meals as an action-opportunity towards AYAs' food intake involved existential feelings including fear of losing their loved ones. Next-of-kin experienced that providing support through and with food was their only avenue of action. However, this sparked feelings of frustration and powerlessness.

Love, joy and necessity - A phenomenological study of food and meals in adolescents and young adults with cancer receiving high-emetogenic chemotherapy.

PURPOSE: This study explored how the phenomenon of meals appeared in the interrelationship between adolescents and young adults (AYAs) receiving high-emetogenic chemotherapy, their next of kin and health professionals in the clinical setting. METHOD: Data were collected by 140 h of participant observation conducted to gain insights into the nature of how meals appeared in the interrelationship between 12 AYAs (age 15-29 years), their next-of-kin and health professionals. The AYAs were patients with oncological and haematological diseases recruited from three university hospital departments. Data analysis was guided by van Manen's hermeneutic-phenomenological approach. RESULTS: The essential meaning of the phenomenon may be characterized by the overarching theme; 'Seeking the joy of meals in the shadow of treatment' and the following three themes: 'Meals as a necessary evil' (AYAs); 'Meals as a matter of love' (next-of-kin); and 'Meals in the shadow of medical treatment' (health professionals). CONCLUSIONS: Meals is a multi-facetted and complex phenomenon that has different meanings to AYAs, next-of-kin and health professionals. To the AYAs, meals emerged as a necessary evil in connection with which urges to eat occurred as glimpses of desire. Prominent feelings of powerlessness and food as love were highlighted by the next-of-kin, whereas food and meals appeared secondary to treatment for health professionals, reflecting the traditional biomedical paradigm. The findings revealed that adopting a holistic approach to AYAs concerning meals can have the potential to increase their food intake.

Delineation of whole heart and substructures in thoracic radiation therapy: National guidelines and contouring atlas by the Danish Multidisciplinary Cancer Groups.

BACKGROUND AND PURPOSE: This study presents Danish consensus guidelines for delineation of the heart and cardiac substructures across relevant Danish Multidisciplinary Cancer Groups. MATERIAL AND METHODS: Consensus guidelines for the heart and cardiac substructures were reached among 15 observers representing the radiotherapy (RT) committees of four Danish Multidisciplinary Cancer Groups. The guidelines were validated on CT scans of 12 patients, each with five independent contour sets. The Sørensen-Dice similarity coefficient (DSC), the distance between the centers of the arteries and the mean surface distance were used to evaluate the inter-observer variation. RESULTS: National guidelines for contouring the heart and cardiac substructures were achieved. The median DSC was 0.78-0.96 for the heart and the four cardiac chambers. For the four substructures of the left ventricle, the median DSC was 0.35-0.57. The coronary arteries were contoured in ten segments, with the best agreement for the left anterior descending coronary artery segments, with a median distance between the arteries ranging from 2.4-4.4 mm. The median variation was 3.7-12.8 mm for the right coronary artery segments and 3.7-6.2 mm for the left circumflex coronary artery segments, with the most pronounced inter-observer variation in the distal segment for all three coronary arteries. CONCLUSION: National guidelines for contouring the heart and cardiac substructures were developed across relevant Danish Multidisciplinary Cancer Groups, where RT dose to the heart is of concern. The inter-observer contour overlap was best for the heart and chambers and decreased for smaller structures.

[Doege-Potter syndrome is a solitary fibrotic tumour often leading to hypoglycaemia].

Doege-Potter syndrome is a rare paraneoplastic syndrome, in which a solitary fibrotic tumour secretes insulin-like growth factor II leading to hypoglycaemia. In this case report, a 70-year-old woman known with a big intra-abdominal tumour was admitted to hospital, unconscious with a blood sugar of 1.8 mmol/l. She was treated with intravenous glucose until surgery, which cured her temporarily. After four months she had relapse and no effect of chemotherapy. Surgery is the only curative treatment for Doege-Potter syndrome, which is important to remember, if a patient has unexplained hypoglycaemia and a tumour.

[Gas-filled liver metastases caused by Clostridium septicum sepsis].

In this case report a 73-year-old male with liver-metastatic colon cancer was admitted to hospital due to severe abdominal pain merely four days after receiving chemotherapy including epidermal growth factor receptor inhibitors. An acute computed tomography revealed gas-filled liver metastases with two possible diagnoses of either a rapid tumour response resulting in tumour necrosis or severe bacterial infection involving liver metastases. Moreover, the patient had an anaerobic infection with Clostridium septicum, and despite relevant treatment he died within 12 hours after admission.
