Lashchenko won the Superkombat Tournament Championship at SUPERKOMBAT World Grand Prix 2011 Final, stopping Ismael Londt with punches to the head in the first round and becoming the first Superkombat World Grand Prix champion in the process.
In his prime he was considered one of the best heavyweight kickboxers in the world, with a career-high ranking at #6 in the world in the LiverKick.com rankings.
Lascenko began his kickboxing career in 2006, mostly fighting under Muay Thai rules. After becoming the Ukrainian Heavyweight Muay Thai Champion in 2007, he went on to win The Honor of Soldier tournament in Moscow, Russia later that year. The tournament kicked off on October 10, 2007 with sixteen competitors. In the opening round, Lascenko beat Sultan Babaev by unanimous decision to qualify for the final eight on December 5. There, he dispatched Andrei Kirsanov via split decision in the quarter-finals, and Yaroslav Zakharov by technical knockout in the semis before taking an extra round unanimous decision over Alexander Oleynik in the final.
On October 27, 2008, he defeated Stepan Kirlish to win the +91 kg gold medal at the 8th Ukrainian Muay Thai Cup.
He made his K-1 debut on November 22, 2008 at the K-1 World Grand Prix 2008 in Riga. He was eliminated from the eight-man tournament at the first stage by Mindaugas Sakalauskas on unanimous decision (10-9, 10-9, 10-9) after an extra round.
On April 13, 2009, Lascenko once again won the +91 kg gold medal at the Ukrainian Muay Thai Championships.
Following this, he entered the IFMA European Amateur Muay Thai Championships in Liepāja, Latvia. He beat Alexei Kudin by decision in the semi-finals on May 20 and Igors Goncarovs by TKO in the final on May 22. Just a day later, he participated in his second K-1 tournament, the K-1 World Grand Prix 2009 in Łódź, in Poland. He made it to the final but lost by knockout to Zabit Samedov, after he had beaten Noel Cadet by TKO and Dmitrij Bezus in the quarters and semis, respectively.
He was given another chance to qualify for the 2009 K-1 World Grand Prix final 16 when he was invited to the K-1 World Grand Prix 2009 in Tokyo Final 16 Qualifying GP in Japan. In the quarter-finals of the tournament, Lascenko faced Sebastian Ciobanu and was able to take a unanimous decision (30-29, 30-28, 30-28) over the Romanian. In the semis, he knocked out Brice Guidon in round two after dropping him with a knee strike to the body in the first. Advancing to the final, he came up against Daniel Ghiţă who stopped him with low kicks inside the first round.
He rebound from this loss by beating Dmitrij Bezus to take the +91 kg gold medal at the 8th Ukrainian Muay Thai Cup on September 21, 2009.
After this, he was invited to compete in the tournament on K-1 World Grand Prix 2010 in Bucharest on May 21, 2010. He was unable to make it past the first stage, as Freddy Kemayo beat him by unanimous decision in the quarter-finals.
He would also go on to lose his next two fights after this, dropping decisions to Alexei Kudin on July 30 in Minsk, Belarus, and Ismael Londt on October 22 in Kazan, Russia. He ended the year with a first-round knockout win over Vasile Popovici in Chişinău, Moldova on December 11.
On May 21, 2011, he took part in the SuperKombat World Grand Prix I 2011 in Bucharest, Romania. It would be the first of four, four-man qualifying tournaments held throughout the year; the winners of the four events would qualify for another four-man Grand Prix at the end of the year to determine the overall champion. In the semi-finals, he stopped Dževad Poturak with a knee to the body in round two, and in the final he KO'd Roman Kleibl with a right hook, also in the second round. This win qualified him for the finals at the end of the year.
The SuperKombat World Grand Prix Final 2011 was held in Darmstadt, Germany on November 19. In the semis, he defeated Erhan Deniz (who he had already beaten back in 2008) via doctor stoppage in round 3. He then advanced into the final against Ismael Londt, the man who had beaten him a year previously. It looked as though the result would be the same this time also as Londt forced Lascenko into the corner and dropped him with a flurry of punches. Lascenko beat the count but was put against the ropes again and, initially, looked overwhelmed. However, Lascenko then dramatically KO'd Londt. With his back against the ropes, he let go his own punch furry and hit Londt with three punches to the head, knocking him out and becoming the first SuperKombat World Grand Prix champion in the process.
He faced Hesdy Gerges at the K-1 World Grand Prix 2012 in Tokyo Final 16 on October 14, 2012. Lascenko was unable to land punches while the Egyptian battered him with low kicks, and lost via unanimous decision.
He was scheduled to have his rubber match with Ismael Londt on November 10, 2012 in Craiova, Romania at the SuperKombat World Grand Prix 2012 Final Elimination, which is the quarter-finals of the SuperKombat World Grand Prix 2012. However, he was forced to pull out of the bout due to injuries sustained in his fight with Gerges and replaced by Daniel Sam. Strangely enough, though, he was then added back to the card to fight Benjamin Adegbuyi, replacing Alexey Ignashov. He was floored twice by Adegbuyi in round one, causing the referee to stop the bout.
He snapped a four-fight losing streak by taking a unanimous decision win over Tomasz Nowak at the K-1 World Grand Prix 2013 in Moldova - Light Heavyweight Tournament in Chișinău, Moldova on March 30, 2013. 
Lascenko was pronounced dead on April 8, 2015 at the Odessa Jewish Hospital in Ukraine after being shot multiple times. According to the Press Service of the Ministry of Interior of the Odessa Oblast, Lascenko was shot in the carotid artery in Odessa during the Deribasovskaya Street night shooting. According to initial information, the cause of quarrel was a woman and generated a conflict between Odessa citizens and a group of eight Caucasians. He was survived by a wife and an 11-month old child - Platon.
