Abstract

Lung cancer is the leading cause of cancer-related death among all types of cancers. In lung cancer patients, hospitalization rates in intensive care units (ICUs) are gradually increasing due to both illness- and treatment-related complications. A 61-year-old male patient who had undergone radiotherapy for small cell lung cancer (SCLC) was admitted to the ICU on the 3rd day of his treatment because of hypercapnic respiratory failure. High-flow oxygen therapy was started. The mass lesion showed rapid progression. Chemotherapy was performed for SCLC which is a chemosensitive tumor.

 Introduction



Small cell lung cancer (SCLC) is one of the most common thoracic tumors and currently constitutes 13.6% of all lung cancers.[1] The tumor is sensitive to chemotherapy and radiotherapy (RT) and can be controlled by chemotherapy in short term. New treatment options and algorithms are used to prolong the survival of these patients. Because of prolonged life expectancy and treatments, hospitalization rates of lung cancer patients in intensive care units (ICUs) are gradually increasing due to both the disease and the complications associated with the treatment. In this article, we report the successful use of chemotherapy in a newly diagnosed SCLC patient admitted to the ICU for respiratory failure.

 Case Report



A 61-year-old male patient was admitted to a thoracic surgery outpatient clinic with complaints of neck swelling, redness of the face, and respiratory distress. Thorax computed tomography (CT) detected a 7 cm × 3.5 cm irregular mass lesion displacing the superior vena cava extending to the paratracheal area posteriorly in the anterior mediastinum [Figure 1]. The patient was diagnosed with SCLC by mediastinoscopy. Due to the large airway compression and vena cava superior syndrome, the patient was decided to undergo emergency radiotherapy, positron emission tomography and cranial magnetic resonance imaging was planned. The patient was directed to an oncology outpatient clinic. The patient whose imaging could not be performed due to increased shortness of breath, was taken to the ICU after the respiratory failure was detected from the emergency clinic that RT was applied on the 3rd day.{Figure 1}

The patient was admitted to the ICU for further examination and treatment because of respiratory failure. On physical examination, his body temperature was 36.8°C, heart rate was 112 beats/min, respiratory rate was 42/min, and blood pressure was 135/63 mmHg. Blood count parameters were erythrocytes erythrocytes 6,77x106/uL, leukocyte count 9100/mm3, hemoglobin value 13.9 g/dL, hematocrit value 44.7%, and platelet count 283,000/mm3. Liver function tests were aspartate aminotransferase 14 U/L, alanine aminotransferase 40 U/L, serum total bilirubin 0.56 mg/dl, and albumin 35.6 g/L. Kidney function test results were as follows: creatinine clearance – 95 ml/min/1.73 m2, creatinine – 0.83 mg/dl, and blood urea nitrogen – 48 mg/dl. Among other biochemical test results, C-reactive protein was 18 mg/L (high risk >3) and procalcitonin was 0.41 ng/ml. Arterial blood gas analysis (room air) results were as follows: pH – 7.31, PaCO2 – 87 mmHg, PaO2 – 41 mmHg, SpO2 – 69.9%, and HCO3 – 40.6 mmol/L. The patient underwent noninvasive mechanical ventilation (NIMV) support. Bilevel-positive airway pressure in spontaneous-time mode was applied with inspiratory positive airway pressure of 15 cm/ H2O, expiratory positive airway pressure of 8 cm/H2O, FiO2 of %60. Fourth-hour blood gas sample values were as follows; pH – 7.39, PaCO2 –68 mmHg, PaO2 – 83.7 mmHg, SpO2– 95.9%, HCO3– 40.6 mmol/L and PaO2/FiO2 ratio – 139. Oxygenation improved with NIMV support and dyspnea and tachypnea decreased. Due to the inefficacy of mask oxygen therapy, high-flow oxygen therapy (HFOT) (heat: 31°C, flow: 50 L/min, FiO2: %65) was applied to the patient who got desaturated after quitting NIMV.

Thrombosis was not detected on lower and upper extremity venous Doppler ultrasonography. There was no bacterial reproduction in sputum, blood, and urine cultures. The lesion showed rapid progression and no signs of infection; chemotherapy was decided for SCLC. Etoposide was given 100 mg/day for 3 days. After one course of chemotherapy, dyspnea decreased. Regression of the lesion was observed on chest X-ray after chemotherapy [Figure 2]. During ICU follow, the patient did not need NIMV and HFOT. The oncological treatment was planned with oxygen supplementation, and the patient was discharged from the ICU. The oncological treatment of the patient was ongoing, and outpatient control was performed in the 3rd month of discharge. SpO2 in room air was 97%, and thorax CT showed significant regression of the lesion [Figure 3].{Figure 2}{Figure 3}

 Discussion



Lung cancer is the leading cause of cancer death worldwide. Worldwide, 2.09 million patients were diagnosed with lung cancer in 2018, and the same year 1.76 million deaths due to lung cancer occurred.[2] It has been reported that the median lifetime for lung cancer is generally 12 months and the 5-year survival ratio is approximately 19%.[3] New treatment options and algorithms applied to patients with lung cancer that are not suitable for surgery, prolong the survival of these patients.[4],[5]

Due to the prolonged life span and the treatments applied, it can be said that the increasing number of lung cancer patients has been followed up in the ICUs for disease-related or treatment-related reasons.[5] The indications for ICU hospitalization may be cancer related (e.g., critical organ involvement and pulmonary embolism), may be associated with treatment (e.g., sepsis and drug toxicity), or may be due to comorbid diseases (e.g., kidney failure, heart failure, and chronic obstructive pulmonary disease attack).[5],[6] However, apart from all these factors, the most common reason for cancer patients to be followed up in the ICU is acute organ failure, usually one or more of the following:

Respiratory failure requiring ventilationRenal failure requiring renal replacement therapySeptic shock with cardiovascular failure requiring vasopressor support.

Other common ICU admission reasons include pulmonary edema, electrolyte disorders, neurological disorders, acute airway obstruction, massive hemoptysis, side effect development against drugs and blood products, and the need for postoperative observation.

High-flow oxygen treatment is a new alternative treatment method used in critically ill patients with severe hypoxemic respiratory failure and slow-flow conventional oxygen supply. High flow oxygen treatement provides not only positive end-expiratory pressure, but also prevents dead space ventilation and reduces work of breathing. It is well tolerated and can be used for a long time.[7] In our case, the reason for admission to the ICU was severe hypoxic respiratory failure developing acutely and high FiO requirement. The HFOT treatment applied reduced the patient's dyspnea, improved oxygenation, and prevented intubation.

SCLC is a malignant solid tumor highly sensitive to chemotherapy and RT (with 50%–70% remission rate).[8] The first-line treatment option for SCLC is chemotherapy. Patients with a good physical condition (Zubrod-Eastern Cooperative Oncology Group-World Health Organization [ZPS] score: 0–2) can also choose standard dose etoposide–cisplatin and carboplatin–etoposide.[9],[10] In patients with a ZPS score of 3–4, a decision must be made with the patient and family, taking into account the physiological functions of the patient and the advantages and disadvantages of the treatment.

Although the benefits of chemotherapy in ICU have been shown in patients with hematologic cancer, there is insufficient evidence to give ICU chemotherapy in lung cancer.[11] However, in critical situations caused by chemotherapy-sensitive tumors, chemotherapy can relieve symptoms and save time for subsequent treatments. In this case, while respiratory failure was treated with HFOT, it was decided to perform simultaneous chemotherapy in our patient whose pathological diagnosis was chemosensitive SCLC and chest radiographs showed that the lesion was rapidly progressing. Besides the respiratory failure, the patient tolerated chemotherapy because of having normal liver and kidney functions. Applied chemotherapy reduced mortality and increased survival.

 Conclusion



Advances in the diagnosis and treatment of ICUs and noninvasive treatment options have a positive effect on the prognosis of malignant patients. However, there is no consensus as to which malignant patients will benefit from treatment. It may be appropriate to give ICU treatment chance, especially for those with acute respiratory failure. If the patient's age, performance status, and comorbid conditions are appropriate and there is a pathological diagnosis sensitive to chemotherapy such as SCLC, oncological treatment without invasive respiratory support such as NIMV and/or HFOT can be applied and treatment of the patient can be continued by controlling the respiratory failure due to the tumor, which is the reason for intensive care.
