Late-onset anastomotic leak following sweet esophagectomy: A case report and review of the literature.

RATIONALE: Late-onset anastomotic leak (AL) is an uncommon but potentially lethal complication after esophagectomy. PATIENT CONCERNS: A 74-year-old male patient was readmitted due to chest distress and chills about 3 months after initial esophagectomy for cancer. DIAGNOSES: The previous endoscopic biopsy revealed primary esophageal squamous cell carcinoma, and sweet esophagectomy with gastric conduit reconstruction was therefore performed. The patient developed AL 3 months after the surgery. INTERVENTIONS: Naso-leakage extraluminal drainage tube was utilized because the symptoms of the patient were aggravated 1 month after the chest tube drainage since his second admission for AL. OUTCOMES: Twenty-one days after naso-leakage extraluminal drainage, the computed tomography images showed the healing of the leakage. Then the patient was discharged from the hospital. LESSONS: Late-onset AL should be kept in mind when the patient complained of chest distress and fever during the follow up after esophagectomy. In addition, naso-leakage extraluminal drainage could be considered for the treatment of AL. Further trials for better evidence are warranted.

Extralobar pulmonary sequestration with elevated serum neuron-specific enolase: A case report and review of the literature.

RATIONALE: Pulmonary sequestration (PS) presenting with elevated serum tumor markers is rare, and it might be misdiagnosed as malignancy. PATIENT CONCERNS: A 26-year-old asymptomatic male patient was admitted because the x-ray showed an intrathoracic lesion. Meanwhile, the serum neuron-specific enolase (NSE) was elevated. Three-dimensional computed tomography angiography revealed an isolated feeding vessel arising from the aorta. DIAGNOSES: Extralobular PS was confirmed by computed tomography angiography and postoperative pathological staining. INTERVENTIONS: Two-port thoracoscopic resection of the sequestrated lobe was performed. OUTCOMES: The serum NSE decreased to within the normal range and persisted during the follow up of 10 months. LESSONS: A thorough work-up should be considered for the PS patients presenting with abnormal serum NSE. Detailed knowledge regarding the relationship between NSE and PS necessitates further studies.

First-line pemetrexed and carboplatin plus anlotinib for epidermal growth factor receptor wild-type and anaplastic lymphoma kinase-negative lung adenocarcinoma with brain metastasis: A case report and review of the literature.

RATIONALE: Brain metastasis (BM) is a serious complication in non-small cell lung cancer (NSCLC) patients. Pemetrexed is one of the preferred agents in nonsquamous NSCLC with BM; however, the traditional chemotherapy demonstrated limited efficacy partly due to drug resistance and the blood-brain barrier. PATIENT CONCERNS: A 52-year-old male non-smoker was admitted for irritating cough, chest distress, and back pain. DIAGNOSES: Epidermal growth factor receptor wild-type, anaplastic lymphoma kinase-negative primary lung adenocarcinoma with an asymptomatic solitary BM (cTxNxM1b, IVA). INTERVENTIONS: Pemetrexed (500 mg/m of body surface area) and carboplatin (area under the curve of 5) were firstly administered every 3 weeks for 3 cycles, followed by pemetrexed/carboplatin plus anlotinib (12 mg daily; 2 weeks on and 1 week off) for another 3 cycles. Then maintenance anlotinib monotherapy was continued for a year, without unacceptable adverse events. OUTCOMES: The BM was slightly enlarged after 3 cycles of pemetrexed/carboplatin; however, a complete remission was achieved after the combination therapy. His intracranial progression-free survival was more than 2 years. LESSONS: Pemetrexed/carboplatin plus anlotinib could be considered for the treatment of epidermal growth factor receptor wild-type, anaplastic lymphoma kinase-negative lung adenocarcinoma with BM. Further well-designed trials are warranted to verify this occasional finding.

First-line albumin-bound paclitaxel/carboplatin plus apatinib in advanced pulmonary sarcomatoid carcinoma: A case series and review of the literature.

RATIONALE: Pulmonary sarcomatoid carcinoma (PSC) is an uncommon type of non-small cell lung cancer, exhibiting aggressive behavior and resistance to the conventional chemoradiotherapy. To date, the optimal treatment for PSC has not been elucidated. PATIENT CONCERNS: Three male patients including a 69-year-old smoker (Case 1), a 45-year-old non-smoker (Case 2), and a 69-year-old smoker (Case 3) were admitted because of cough, back pain, and loss of body weight respectively. DIAGNOSES: Radiographical examinations in these patients showed bulky intrathoracic lesions, which were pathologically diagnosed as PSC staging III-IV by computed tomography-guided percutaneous biopsy and endoscopy. INTERVENTIONS: Immunotherapy was not covered by their health insurance and they refused immune checkpoint inhibitors for financial reasons. In addition, a radical resection was not appropriate due to the advanced staging of these lesions. Therefore, first-line albumin-bound paclitaxel (nab-paclitaxel, 260 mg/m of the body surface area) and carboplatin (area under curve 5) combined with oral apatinib (425 mg, daily) were administered empirically. OUTCOMES: Two patients achieved a partial response and the other case showed stable disease lasting for more than 6 months. However, 1 of them indicated progression on the 7-month follow up. LESSONS: Nab-paclitaxel/carboplatin plus apatinib showed limited short-term efficacy in advanced, unresectable PSC. The rapid resistance of PSC to the current therapeutic regimen necessitates further researches, as more effective agents are urgently needed.

Remote intervention using smartphone for rural women suffering from premenstrual syndrome: A propensity score matched analysis.

Timely treatment of premenstrual syndrome (PMS) is not always available for rural women, because the local medical resources are insufficient. The efficacy of remote intervention by smartphone on PMS has not been confirmed.A retrospective analysis was performed on rural PMS patients between January 2014 and December 2015. After a propensity score matched analysis, 60 patients were enrolled and evenly divided into remote group and outpatient group. Multidisciplinary therapy including cognitive-behavioral therapy (CBT), oral medication, and physical exercise education was used individually, in accordance with their symptoms evaluated by Daily Record of Severity of Problems (DRSP) questionnaire. Patients in remote group utilized WeChat software by smartphone for therapy guidance, while those in outpatient group attended face-to-face interview. Their DRSP scores in 5 new menstrual cycles after therapy were recorded. Then, they were followed up for 1 year.Total DRSP scores of the cases in both groups after initial intervention were less than those before therapy (P < .001), without group difference (P > .05). However, patients in remote group indicated a higher satisfactory rate than the outpatient group (P = .03). On the 1-year follow up, patients in both groups demonstrated similar DRSP scores (P = .07), but the satisfactory rate in remote group was encouragingly higher than that in the outpatient group (P = .02).The efficacy of remote intervention using smartphone on PMS is noninferior to traditional outpatient visits. Nevertheless, high-quality trials are needed.

A rare case of Merkel cell carcinoma presenting as a giant intra-thoracic mass: A case report and review of the literature.

RATIONALE: Merkel cell carcinoma (MCC) is an aggressive neuroendocrine-derived cutaneous cancer. Ectopic or single metastatic MCC located in thorax is extremely rare; meanwhile, its definite management has not been elucidated yet. PATIENT CONCERNS: A 64-year-old female patient with a giant mass located in her left thorax was presented for stuffy pain of left chest for 6 months and fever for half a month. She underwent radical resection of vulvar MCC 10 years ago. DIAGNOSES: Computed tomography (CT)-guided biopsy of the intrathoracic mass revealed a diagnosis of MCC, without synchronous urogenital lesions on pelvic CT images. INTERVENTIONS: This bulky tumor was completely resected via thoracotomy, along with the adjacent pulmonary lobe, pericardium, pleura, and diaphragm. OUTCOMES: The patient survived without local-regional recurrence or distant metastasis during the follow-up of 1 year up to now. LESSONS: Ectopic or single metastatic MCC should be considered in the differential diagnosis of intrathoracic tumors, especially in patients with a history of MCC. Besides, a timely surgery combined with chemotherapy is effective for this disease.

A long-term survivor with esophageal melanoma and pulmonary metastasis after single-stage esophagectomy and lobectomy: Case report and literature review.

RATIONALE: The optimal therapeutic regimen for primary malignant melanoma of the esophagus (PMME) need to be further elucidated. Besides, the efficacy of surgery for PMME with remote metastasis is uncertain for its rarity. PATIENT CONCERNS: Herein a previously healthy patient was admitted for dysphagia and fatigue, without significant weight loss. DIAGNOSES: The pathological and molecular tests revealed his diagnosis of BRAF-mutant, advanced PMME with localized pulmonary metastasis. INTERVENTIONS: Single-stage Ivor-Lewis esophagectomy and lobectomy were performed successfully, followed by 4 cycles of conventional chemotherapy, and concurrent high-dose interferon lasting for 1 year. OUTCOMES: The patient survived without logo-regional recurrence or remote metastasis during the follow up of two and a half years up to now. LESSONS: Timely resection of localized primary and metastatic lesions might deliver a chance to obtain better prognosis for selected PMME patients; however, high-quality trials with longer follow-up are needed.

Hepatectomy combined with microwave ablation of the spleen for treatment of hepatocellular carcinoma complicated with splenomegaly: A retrospective study.

The present retrospective study aimed to investigate the mid-term safety and efficacy of hepatectomy combined with microwave ablation of the partial spleen for treatment of liver cancer complicated with hypersplenism. A retrospective analysis was performed on 23 patients who underwent hepatectomy combined with microwave ablation of the partial spleen for liver cancer, complicated with hypersplenism that was secondary to cirrhosis. The splenic and ablated volumes were calculated according to a contrast-enhanced computed tomography scan prior to and 2 weeks after the operation. Complete blood count and liver function tests were examined prior to and following the surgery, and complications and changes in the blood tests were monitored for 6 months. Over this period of investigation, the splenic volume was reduced by a mean value of 34.0%. The levels of serum alanine aminotransferase and aspartate aminotransferase were increased on the first day after the operation (P<0.05), although they recovered to the normal level within 1 week (P<0.05). The total level of bilirubin increased slightly, along with moderately decreased levels of albumin and cholinesterase on the first day, although these changes were not significant compared with the baseline (P>0.05). The white blood cell count was persistently significantly higher compared with the baseline over the course of the 6 months (P>0.05). The platelet count did not increase significantly for the first week after the operation (P>0.05); however, it was revealed to be significantly increased 1 month after the surgery (P<0.05). No significant complications were occurred during the follow-up period. In conclusion, hepatectomy combined with microwave ablation of the spleen was demonstrated to be a safe and effective procedure for patients with liver cancer and hypersplenism in the mid-term.

A recurrence-free survivor with chemotherapy-refractory small cell lung cancer after pneumonectomy: A case report and review of the literature.

RATIONALE: The optimal therapeutic regimen for chemotherapy-refractory and node-positive small-cell lung cancer (SCLC) is criticizable for the lack of evidence. PATIENT CONCERNS: A patient with locally advanced SCLC was insensitive to the first-line chemotherapy of etoposide, irinotecan, and cisplatin. DIAGNOSES: The patient was diagnosed as SCLC with mediastinal lymph node metastasis by pathological staining. INTERVENTIONS: Salvage pneumonectomy and systematic lymph node dissection combined with oral apatinib and mediastinal radiotherapy were performed for him. OUTCOMES: The patient survived for more than 2 years without recurrence after the operation and adjuvant therapy. LESSONS: For patients with chemotherapy-resistant but resectable SCLC, a timely resection combined with postoperative radiotherapy and apatinib might be effective.

A rare case of cavitary lung cancer complicated with mycotic pneumonia and bullous emphysema: A case report and review of the literature.

RATIONALE: The accurate diagnosis and staging of cavitary lung cancer is challenging but essential for the choice of therapy; therefore, the differential diagnosis of cystic pulmonary lesions needs to be elucidated. PATIENT CONCERNS: A patient was admitted with multifocal thin-walled cystic lesions in chest computed tomography. DIAGNOSES: The patient had been diagnosed as heterogeneous bullous emphysema pathologically about 3 years ago. His diagnosis turned out to be metastatic cavitary lung cancer complicated with fungal pneumonia this time. INTERVENTIONS: The patient underwent lung volume reduction surgery during his first hospitalization. Concurrent systemic chemotherapy and whole brain radiotherapy were administered after the diagnosis of cystic lung cancer. OUTCOMES: The patient was lost to follow-up after the chemoradiotherapy. LESSONS: Cavitary lung cancer should always be kept in mind during differential diagnosis of pulmonary cystic lesions. Pathological diagnosis by biopsy and surgery could be considered to avoid delayed treatment of malignancy.
